Twice a year, around 1,000 new Blue Book trainees land in Brussels within the same two-week window — the European Commission’s own figure. The European Commission will not help a single one of them find a place to live.
That’s stated plainly on the Commission’s own site: accommodation is the trainee’s responsibility. Budget for a deposit, usually one to two months’ rent. Expect living costs higher than back home. Then you’re pointed toward the Trainees’ Committee and a few Facebook groups, and left to sort it out while 900 other people search the same listings at the same time.
The lease length nobody warns you about
A Blue Book traineeship runs five months. Most Belgian leases don’t. The standard “3-6-9” structure that governs most Brussels rentals is built for people staying years. A lot of trainees get turned away by landlords who don’t want a five-month tenant. Others sign something much longer than they need and hope to sublet later, or pay a cancellation penalty when the traineeship ends and the lease doesn’t.
When to actually start looking
Four to six weeks before arrival is realistic for anything with a real inspection or video call. Much earlier than that and most landlords won’t commit to a date that far out. Much later and you’re competing with the same wave of trainees for whatever’s left in the last two weeks before the intake.
If nothing’s confirmed by the time you land, that’s normal, not a crisis. A short-term booking, a week or two on Airbnb or a serviced studio, buys time to view places in person instead of committing to anything sight unseen.
Where trainees actually search
Immoweb and the general platforms first. Facebook groups built specifically for Brussels housing and EU trainees, where a lot of room-shares and sublets get posted before they ever hit Immoweb. A handful of platforms built for shorter stays, some of which give a discount to trainees who show their t-card. All of it works. All of it also means coordinating viewings, deposits and contracts from another country, often before setting foot in Brussels.
The part that matters more than the rent
The trainee community is more direct about this than the official guidance. Don’t deal with anyone who won’t get on a call or won’t let you view the room in person or by video. Google the name before sending anything. Make sure any payment goes to a real, verifiable account, not a “manager” who’s supposedly abroad and can only take a transfer. Trust your gut if something feels off.
A short list worth keeping on your phone while you’re searching:
- Video call or in-person visit before any money moves
- Landlord or agency name, googled
- Payment to a verifiable business or personal account, never a wire to a stranger “holding the keys”
- A written contract, even a simple one, before the deposit
That’s solid advice, and it’s also a sign of how much verification work lands on one person: arriving somewhere new, renting for the first time in their life, often doing it in a language that isn’t theirs.
The admin nobody mentions until it delays your first paycheck
Opening a Belgian bank account isn’t required to do a traineeship, but registering with the local commune often is, and that registration can take weeks depending on the commune and whether your building already has other registered tenants. Trainees who move into a building with an existing, organized landlord or operator tend to get this sorted faster than trainees dealing with a private individual landlord juggling it alongside a day job.
Picking a neighborhood on a trainee budget
Etterbeek sits right next to the Schuman/EU quarter. For a five-month stay where minimizing commute time actually matters, it’s the direct option.
Ixelles, especially around Flagey and Châtelain, trades a slightly longer commute for more restaurants, bars and the kind of social life that makes five months feel like more than a work placement.
Saint-Gilles works for trainees who want both: a walkable trip to the EU quarter and a neighborhood with its own identity, markets, and a lower density of other EU trainees if building a life outside the institutional bubble matters to you.
Why coliving ends up being the practical choice
Three things end up deciding whether the first month goes smoothly: a lease length that actually matches five months, a landlord or operator you can verify before committing to anything, and not spending your first weekend in Brussels alone in a studio. For most incoming trainees, that last one matters more than they expect going in.
Coliving fits a five-month stint better than a solo lease for exactly these reasons. Room contracts at TwentySeven are built to match traineeship-length stays rather than the standard Belgian term. You’re dealing with a managed, verifiable operator instead of a stranger from a Facebook group, so the entire scam checklist above is already handled before you arrive. And you move into a building with other people already living there, not an empty apartment you have to build a social life around from zero.

FAQ
Does the European Commission provide housing for Blue Book trainees?
No. The Commission says it directly: accommodation is entirely the trainee’s responsibility. It points incoming trainees to the Trainees’ Committee and housing Facebook groups as starting points.
Do I need a full Belgian lease for a 5-month traineeship?
Not if you look for short-term or coliving arrangements specifically. The standard 3-6-9 lease structure isn’t built for a single semester, and breaking it early usually costs a penalty.
Is coliving a good fit for EU trainees?
It solves two problems at once for a five-month stay: a lease length that matches the traineeship, and a social circle from day one instead of starting from zero.
Which neighborhoods make sense for a traineeship near the EU institutions?
Etterbeek for the shortest commute, Ixelles for social life around Flagey and Châtelain, Saint-Gilles for a mix of both with a bit more distance from the EU bubble.
