Vinc` is a very hospitable and responsive host. He always answered for our messages very fast. Also he gave us good advices about interesting places we should to visit in Brussel and out of it.
As for the apartment, it looks like the photos - really bright and cozy. There are all the necessary things to live comfortably in it. It is located near metro station (about 5 minutes by foot), also you can walk to the center of Brussels by foot (about 15 minutes). The nearest train station is about 10-15 minutes from apartment, so you can go from and to airport very fast without using other kinds of transport. In the nearest neighborhood there are supermarkets, bars and shops.
So, I can confidently recommend this accommodation, if you want to spend great time in Brussels.
