This is a very spacious apartment in a great location if you want to explore Brussels and the rest of Belgium. It is super close to one of the main train stations (short walking distance) as well as trams, metro, and buses. Even though it is a busy area the apartment is set back from any traffic noise, you literally can't hear a single car.
We loved the place, but 2 things to be aware of: 1) if you travel with somebody you aren't super close with or 2 couples, then it might be not the right place. the second bedroom doesn't have a properly closing door, it's only a sliding door with significant gaps into the living room (we didn't mind, but I would have if I had traveled with others); 2) this is a very culturally diverse area (little locale middle eastern grocer with a great selection of fresh fruit is on the corner of the block), personally I loved it, but I'm also very used to it, if that's not your kinda hood, then pick another place.
One last thing, when leaving the apartment in the morning or returning from our excursions in the afternoon we often ran into other occupants of the apartment complex...everybody was utterly delightful and friendly...very much a reflection of the people in Belgium we encountered on our trip. So if you want to live like a local and have the comforts of a very modern and spacious apartment, then this is the place for you.
