Had a good stay at Sams! It’s a very clean studio that has all the amenities you would need.
One downside is that it’s a bit further away from Brussels center (35 min by public transport). Also, it is along a main road so there is some traffic noise.
And just a tip: don’t take the elevator- got stuck in it haha. The studio is 4 floors up so if stairs are difficult for you that is something to consider.
All in all though a good stay.
