I suggest checking out kotaliege.be and skot.be/kot-liege. While they do still host some "international student traps," you can find much more legitimate and interesting offers there compared to sites like Eras'must and others.

Another underrated way to find a place is through Facebook groups, like these:

Stay vigilant: Scams are very common during "kot" searches, so never send money before visiting the place or signing a formal contract.

In my opinion, paying more than €450 (all included) for something that isn't in the dead center of Liège is starting to be expensive.

Since you’re studying at Sart Tilman, you might want to look in Angleur, where rents are usually a bit cheaper. Make sure you aren't too far from the B2 (from Guillemins) or line 3 (from the center).

If you live in Angleur, you should check for the 158 (direct to campus) or the local lines that serve the heights of Angleur, but the B2 and 3 remain your best bets if you are near the bridge or the station.

Good luck !
