We were a group of 6 (3 couples) and this home worked very good for us. The location was great, close to transit stops and a grocery store near-by. Communication with the host was great and was helpful with how to arrive from the airport.
Like others have mentions, it advertised a clothes washer, but was not working and we had hoped to use it, as we were in the middle of our trip. It looks like from other reviews at least for over a year the washer has not worked, and the listing still shows it has a washer (I just looked), so double check if that is important.
In addition, like one other reviewer mentioned, the spiral staircase in the home is very narrow and steep, and would be difficult for some (small children & older adults), but we did use the building hallway staircase for the majority of the time between floors, and that was fine.
The furnishings are a bit older, but overall we enjoyed our stay here and would stay again, if visiting Brussels again.
