Social media is the main way students advertise housing in Maastricht. If you’re looking for a room in a student house, to be housemates with older students who can show you around the city, then this is the best way to find people with opportunities for you. This is how most students live and it’s a lot cheaper than having your own studio!
Unfortunately, these pages are also the places scammers target the most. Be careful of anything that looks too good to be true. Most student houses will want to meet you first, but you should always be able to look round a place or at least insist on a skype call before signing or paying the deposit.
A contract should always be signed before paying the deposit, and if you’re ever asked to transfer money to a bank account with an IBAN that doesn’t begin with NL then beware. This page is directed at housing in Amsterdam but has good information about avoiding scams.
