Most people arrive in Brussels with the same question: where do I even start?
You have a new job or traineeship, a move-in date, and roughly 48 hours to figure out everything else. The Belgian administration has a reputation. Rent is higher than you expected. The city has four neighborhoods that look identical on Google Maps but feel completely different in real life.
This guide cuts through that. It’s based on 20 years of housing thousands of expats in Brussels: EU officials, Schuman trainees, consultants, pharma managers, NGO workers. We know what catches people off guard, what’s actually easy, and what takes longer than it should.
What Brussels Is, Actually
Brussels is three cities compressed into one.
The first is the EU bubble: the European Quarter, the institutions, the policy world around Schuman and Maelbeek. Dense, international, driven by a two-year rotation of officials who want a good apartment near their office.
The second is the expat Brussels that everyone discovers at some point. Ixelles, the Châtelain market on Saturday mornings, Place Flagey, the bars on Rue de la Paix. Young professionals, diplomats, professionals in their 30s who came for two years and stayed for ten.
The third is the local city: Saint-Gilles, Molenbeek, Laeken, Forest. Brussels residents who have nothing to do with EU institutions and have been here all their lives.
Most expats end up primarily in the second. This guide is written for them.
Key facts at a glance:
- Population: ~1.25 million (Brussels Capital Region) (IBSA Mini-Bru 2025)
- Official languages: French and Dutch (but English gets you everywhere)
- Average apartment rent: €1,376/month (unfurnished, 2025) (IBSA 2025)
- Brussels rents up +18% since 2021
- Cost of living: lower than London or Zurich, higher than Warsaw or Lisbon
The Neighborhoods, Honestly
Ixelles / Châtelain: the international default
If you’re an expat and you don’t know where to live, you end up in Ixelles. Most people end up in Ixelles. There’s a reason for that.
Place Châtelain has a market every Wednesday. Place Flagey has the best weekend brunch options in the city. The whole area is walkable, international, with restaurants, coffee shops, and pharmacies on every block. Rents are high. A furnished studio here will run €900–1,200/month all-inclusive , but the lifestyle absorbs the cost quickly.
If you’re here for a 5-month Blue Book traineeship, Ixelles is the neighborhood where you’ll actually meet people. If you’re here long-term, it’s where you’ll build a real routine.
Etterbeek / European Quarter: for EU people
Etterbeek sits right against the European institutions. The European Commission, Parliament, and Council are all within walking distance or a short metro ride (Schuman, Maelbeek, Arts-Loi). The neighborhood itself is calmer than Ixelles: less nightlife, more practical. Supermarkets, restaurants, the Cinquantenaire park for running.
The tradeoff is that it can feel like an extension of the office. A lot of EU officials choose Ixelles instead precisely because they want to leave work behind when they go home.
That said: if your commute matters, Etterbeek is hard to beat.
Saint-Gilles / Parvis: value + authenticity
Saint-Gilles has changed fast over the past five years. The area around Place du Parvis de Saint-Gilles and Rue Lepic has become one of the best places in Brussels to eat and drink: genuine restaurants, independent coffee shops, a younger demographic.
Rents are meaningfully lower than Ixelles or Etterbeek. Transport is solid: several tram and metro lines, and easy access to central Brussels.
The perception that Saint-Gilles is “rough” is outdated. It’s real Brussels, which some expats prefer and others don’t. If you’re on a tighter budget or you want something with more local character and less expat bubble, start here.
Brussels Centre
The city center gets a bad reputation from expats who visited once and saw the tourist-facing version. The reality is more nuanced. Areas like Ixelles-adjacent Sablon, the area around Flagey spilling into Elsene, and the Saint-Josse-adjacent streets are perfectly liveable.
That said, for most expats, central Brussels makes sense if you’re here for a short stay and want easy access to every part of the city via the main metro lines.
What Things Actually Cost
The sticker shock of Brussels rents hits everyone. Here’s an honest picture.
Unfurnished apartments (standard Belgian lease):
- Studio (30–40m²): €800–1,100/month + charges (electricity, heating, internet all extra)
- 1-bedroom: €1,100–1,500/month + charges
- Belgian “3-6-9” lease: standard contract is 3 years minimum, with break clauses at year 1 and year 2 requiring 3-months’ notice
Furnished, all-inclusive apartments:
- Studios from €790/month (WiFi, utilities, maintenance, furniture included)
- 1-bedroom from €950/month
- Co-living rooms from €595/month all-inclusive
That gap matters. An unfurnished apartment at €1,100/month quickly becomes €1,350–1,450/month once you add electricity, heating, internet, and renter’s insurance. You also need to buy or rent furniture, wait for a deposit return that can take months, and commit to a 1–3 year minimum.
Other costs to expect:
- Groceries: €250–350/month for one person
- Public transport: STIB card from €55/month (unlimited metro/bus/tram)
- Eating out: €15–25/meal at a mid-range restaurant, lunch menus €12–16
- Brussels has no income tax rebate for expats (unlike the Netherlands), but the EU offers specific expat tax status for officials
Housing: The Decision That Shapes Everything
Most expats arrive with one of two housing problems.
The first: you have 10 days before your traineeship or contract starts and no idea where to look. The Belgian rental market is competitive: some listings attract 100+ applicants. By the time you’ve arranged viewings from abroad, the apartment is gone.
The second: you find a furnished apartment, move in, and six months later you’re either looking to extend a lease that doesn’t allow it, or you’re stuck in a 3-year Belgian contract when you only need 12 more months.
All-inclusive furnished apartments solve both. No furniture to buy, no utility contracts to set up, no Belgian lease to navigate. You move in with a suitcase, everything is already there: WiFi, water, electricity, maintenance.
At TwentySeven, flexible contracts start from 1 month. Most tenants stay 4–18 months. The majority are exactly who you’d expect: EU trainees at the beginning of a 5-month Blue Book, consultants on 12-month secondments, professionals relocating for a new role who need time to decide whether Brussels is permanent.

The Co-Living Question
Co-living in Brussels has evolved from “student shared house” to something much more structured.
A well-run co-living setup means a private furnished room in a managed flat: common areas maintained, WiFi, utilities, cleaning included, no disputes over the electricity bill. Prices typically start from €595/month all-inclusive, compared to €800–900 for a studio where you’re managing everything alone.
Price matters. Week one matters more.
Arriving in a new city alone is a specific kind of hard. You know nobody, you don’t have routines yet, and the city hasn’t made sense yet. Co-living puts you in a flat with other people in exactly the same situation. The network builds fast.
For EU trainees especially. A 5-month Blue Book traineeship is short enough that building a social life from scratch in an empty studio is genuinely difficult. Most Schuman trainees who chose co-living say it was the right call.

Admin: What Actually Needs to Happen
Belgian administration has a reputation. It’s partially earned.
Commune registration: do this first
Within 8 working days of arriving in Belgium, you’re legally required to register at your local commune (municipality). In practice, nobody comes looking for you if you miss the deadline, but you need that registration to open a bank account, get a national ID, or access various services.
The main communes for expats: Ixelles (Elsene), Etterbeek, Saint-Gilles, Brussels City. Each commune has its own counter with its own opening hours. Check the website before showing up.
You’ll need: proof of identity (passport), proof of address (rental contract or letter from landlord), and depending on your situation, documents from your employer or institution.
After registration, a commune agent comes to your home to verify the address. This sounds archaic because it is. Plan for it to take 2–4 weeks in total before you receive your national registration number.
National number (numéro national / rijksregisternummer)
This number follows you through everything Belgian: bank accounts, health insurance, tax filings. You get it through the commune registration process.
Belgian bank account
You need one. Transferring rent, paying bills, receiving Belgian payslips all require a local account. BNP Paribas Fortis and ING are the most widely used by expats. Belfius and KBC work too. Most banks now have straightforward online opening processes, but some branches still require in-person visits. Expect 1–2 weeks to receive the card.
EU officials and trainees: You have a specific status: the Staff Regulations cover your situation differently. Check with your institution’s HR department on registration requirements and whether you need to register with the commune (some EU officials have a specific exemption or different process).
Getting Around Brussels
Brussels is small enough that most of the city is accessible by public transport within 30 minutes.
STIB / De Lijn / TEC: The STIB network covers metro, tram, and bus across Brussels Capital Region. A monthly unlimited card (MOBIB) costs €55 for Brussels only, €75 with Walloon connections. Buy it at any STIB point of sale or online.
Cycling: Brussels has steadily improved its cycling infrastructure. The city is flat in most expat neighborhoods, and Villo! (the bike-sharing system) covers the main areas. Not perfect. Some streets are genuinely dangerous for cyclists: but a viable daily option for short distances.
Train (SNCB): Brussels has five train stations, including Central, Midi, and Schuman. For trips to Ghent (30 min), Bruges (55 min), Antwerp (40 min), or Amsterdam (2h), the train beats everything.
Car: You don’t need one. Parking in most expat neighborhoods is expensive or impossible. Car-sharing options (Cambio, Poppy) work well for out-of-town trips.
Social Life: Finding Your Community
Brussels rewards people who make an effort. It’s not Berlin or London. It won’t come to you. But the expat community is genuinely large and well-organized.
InterNations has an active Brussels chapter with regular events. Brussels expat Facebook groups are chaotic but useful: flat shares, secondhand furniture, weekend trips.
The EU traineeship community is its own ecosystem. Five-month Blue Book cycles mean there are always new cohorts arriving in February and October. The social life around traineeships is intense by necessity. Everyone is temporary, everyone wants to make the most of it.
For a longer-term Brussels life: the neighborhoods you choose determine your social circle. Ixelles gives you international, Châtelain-centered social life. Saint-Gilles gives you a mix of expats and locals. Etterbeek gives you EU colleagues.
Sports: Brussels has good gym options: Basic-Fit for budget, Urban Athlete for crossfit, several running clubs that train around Bois de la Cambre.
Frequently Asked Questions About Living in Brussels
How expensive is Brussels compared to other European capitals?
Brussels is moderately expensive: cheaper than London, Amsterdam, or Zurich. More expensive than Warsaw, Prague, or Lisbon. Rent is the main cost driver. A well-managed all-inclusive furnished apartment from €790/month makes the comparison much more favorable.
Do I need to speak French or Dutch to live in Brussels?
No. English is widely spoken in international and EU circles. In shops, restaurants, and local administration, some French helps, but you can operate entirely in English in most expat-facing contexts. Learning basic French (bonjour, merci, un café s’il vous plaît) goes a long way culturally even if it’s not strictly necessary.
What’s the best neighborhood for EU trainees in Brussels?
Ixelles (especially around Châtelain and Flagey) and Saint-Gilles are the most popular for EU trainees. They offer the best combination of social life, access to the institutions via metro, and furnished co-living options in the right price range.
How long does it take to find housing in Brussels?
The market is tight. Unfurnished apartments in good locations can receive 50–100+ applications. For furnished all-inclusive options with flexible leases, the process is faster, typically 1–3 days from inquiry to contract signature with an operator like TwentySeven.
Is co-living a good option in Brussels?
For stays under 12 months, absolutely. All-inclusive co-living from €595/month eliminates the Belgian lease complexity, furniture logistics, and utility management. For a 5-month traineeship, the social component is often the deciding factor.
How do I register at the commune in Brussels?
Go to your local commune within 8 working days of arrival with your passport and rental contract (or proof of address). Request registration as a foreign national. A commune agent will visit to verify your address, and you’ll receive your national registration number within a few weeks. Some communes have online appointment systems. Check their website first.
Can I bring a pet to Brussels?
Yes. Belgium is pet-friendly. Most residential leases require landlord approval for pets. TwentySeven’s pet policy varies by property. Ask when you inquire.
Before You Move
The one thing that catches expats most off guard: how competitive the Brussels housing market has become.
Rents are up 18% since 2021. A decent unfurnished 1-bedroom in Ixelles that cost €1,100 two years ago costs €1,300 today. The good furnished apartments go fast, sometimes within 24 hours of listing.
The practical answer is to start looking 3–4 weeks before your arrival date, have your documents ready (passport, contract or traineeship confirmation), and be prepared to make a decision quickly when you find the right place.
TwentySeven has furnished apartments and co-living rooms in Ixelles, Etterbeek, and Saint-Gilles, all-inclusive, flexible contracts from 1 month, available for EU trainees, professionals, and expats relocating to Brussels. No Belgian lease, no furniture logistics, maintenance covered 24/7.
