The Appartment itself is amazing, clean and cosy. The Metro is right across the street and a convinience Store is and the base of the house or across the street in the Metro Station. So you have everything you need close by. I would stay here again.
Small sidenote: The area around the house (that itself seems pretty new) is extremly rundown and dirty. Its hard to get a parking spot (as to be expected from Brussel). So this is fine if you want to explore the city center and maybe not come by car (otherwise you have to be lucky and parking is only for 5h most the time). But the surrounding area is to be avoided in my opinion.
