I am visiting Belgium for the first time, i am looking for decent accomodation during my stay for around two weeks, any suggestion/proposal is welcome
Apart from many companies that deal with hotels, if you're staying for a while I'd consider an apartment. I've used this company many times before and they have a great selection apartments in Brussels
I would recommend staying around the city center rather than the EU quarter because there's a bit more life.
If you go to Brugge which I suggest most people do, the Lybeer Hostel is a good place to crash, with very friendly hosts.
