As others have mentioned earlier the wifi needs some patience (and the TV works on wifi) and if you open the window the noise of cars passing by kind of echos up to the room. I believe they have another room facing the other side which might be more quiet.
Other than that the location is terrific-close to metro and bus stop, there are lot of grocery stores around. The room is huge and clean. I didn't get to meet Luca but his mother Adriana checked us in and she was a great help during the whole stay.
Overall I would totally recommend Luca's place; it's a great place for the value and Bruxelles is a wonderful city itself and to explore around Europe!
