The hosts were really friendly and welcoming. They gave us a map of Brussels and some suggestions on where to eat and go sightseeing.
The area is very nice and just a few minute's from the Grand Place and other attractions. If you need to go to the European area where the institutions are, bus numbed 27 will take you there in about 10 minutes.
I was there with three friends and we all enjoyed our stay :) the flat is beautiful and extremely clean!
We would definitely come back here in the future, it was a great choice!
