Three job offers, three visas, three flights booked. And still no idea where you’re going to sleep in six weeks.
That’s the actual starting point for most people moving to Brussels for work. Not "which neighbourhood has the best coffee", but "I have one weekend to find a place before I start, and I don’t know this city yet."
You’re not alone in that scramble. In 2024, Brussels gained 19,398 international arrivals, according to BISA, the region’s statistics institute. Nearly 40% of Brussels residents are now non-Belgian. The housing market is used to newcomers landing fast; that’s exactly why coliving, flatsharing, and short-term studios all exist as distinct options here.
There are three real options: coliving, flatsharing, or renting your own studio. Each one solves a different problem. None of them is objectively "the best." Here’s how to actually pick.
Start with these three questions
How long are you staying? Under a year, and signing a 3-year Belgian lease for a studio makes no financial sense. Over two years, and paying a coliving premium every month stops being worth it.
How much admin do you want to do yourself? Setting up electricity, internet, water, and a Belgian bank account takes weeks if nobody’s done it before. Some people don’t mind. Most people, arriving with a new job starting in ten days, really do.
How much do you want to control who you live with? A flatshare means inheriting whoever’s already there, or whoever answers your ad. Coliving means a managed community with some vetting behind it. A studio means nobody, ever, which is either exactly what you want or the loneliest six months of your career.
Answer those three, and the choice usually makes itself.
Option 1: Coliving
Coliving is a furnished private room in a shared house, with one operator managing the whole thing instead of a landlord and a pile of roommates.
What’s actually included, at least at TwentySeven: your own room, a shared kitchen and living room, WiFi, utilities, and weekly cleaning of common areas, all on one monthly invoice. Contracts start from 1 month. No 3-year lease, no deposit negotiation, no guarantor scramble in most cases.
The tradeoff is the one everyone assumes: you’re sharing space with people you didn’t choose. In practice, most coliving houses skew toward the same profile, young professionals, EU trainees, people on 4-12 month assignments, which means the "strangers" are usually in a similar life stage to you.
Rooms start at €595/month all-inclusive, across properties in Ixelles, Etterbeek and Saint-Gilles.
Option 2: Flatsharing
A flatshare is the DIY version: you answer an ad, meet the existing tenants, and if it clicks, you move in and split whatever needs splitting.
It’s usually the cheapest per month of the three. It’s also the one with the least predictability. You’re relying on a Facebook group post or a listing site to represent the flat and the people in it accurately, and in a lot of cases you’re signing onto an existing shared lease where you and your flatmates are jointly liable for the full rent, not just your share. If someone stops paying or moves out early, that becomes your problem too.
We wrote a full breakdown of that specific risk in our Coliving vs Colocation guide, because it’s the part most people don’t find out about until it happens.
Flatsharing works best if you already have contacts in Brussels, you’re staying long enough to make the admin worth it, and you want the lowest monthly cost above everything else.
Option 3: Renting your own studio
A studio gives you what neither of the other two can: full privacy, no shared kitchen, no negotiating the thermostat with anyone.
It also comes with the most setup. Belgian studio and apartment leases default to a 9-year term structured in three-year periods (the "3-6-9"), under the Brussels Housing Code, with financial penalties if you break it in year one. You’re furnishing the place yourself, opening accounts for electricity, water and internet in your own name, and putting down a deposit that can take months to get back at the end.
For someone relocating for two-plus years, or a couple who wants a real home rather than a temporary base, that setup cost amortises fine. For someone on a 5-month contract, it rarely does.
The honest comparison
| Coliving | Flatshare | Studio | |
|---|---|---|---|
| Contract length | From 1 month | Usually tied to existing lease | Typically 3 years |
| Setup time | Days | Days to weeks | Weeks |
| Bills | One invoice | Split between tenants | All in your name |
| Financial risk if others don’t pay | None, individual contract | Yes, joint liability | None, but no flatmates to share cost |
| Privacy | Private room, shared common areas | Private room, shared common areas | Full |
| Best for | Stays under a year, fast moves, professionals who want zero admin | Long stays, existing contacts, lowest monthly cost | 2+ years, couples, full independence |
Bottom line
If you need to be settled within two weeks and you don’t want your housing to depend on people you’ve never met, coliving is built for exactly that. If you’re staying for years and want full independence, a studio is worth the setup. Flatsharing sits in between: cheaper than both, but only as reliable as the lease and the people on it.
Whichever you land on, check what "all-inclusive" actually means before you sign; some listings use the word loosely.
FAQ
Which is cheapest: coliving, flatshare, or studio?
Flatsharing usually wins on rent alone. Once you add setup time, deposit risk, and the cost of furnishing a studio, the gap narrows a lot.
Can I switch from coliving to a studio later?
Yes, plenty of people use coliving as a landing pad for the first 6-12 months, then move into a long-term lease once they know the city and don’t need to rush a decision.
Do EU trainees usually choose coliving?
It’s the most common profile in our co-living properties: 5-month Blue Book contracts, arriving with little lead time, needing something furnished and near the European Quarter or in Ixelles.
Is a Belgian bank account required for any of these?
Depends on the contract and your nationality. For coliving, our team checks this with you individually before signing. For a studio or standard lease, most landlords require one.
