The apartment is a nice place to stay in Brussel. There is enough space for two people but it would be too small for three, for example when you travel with a child.
All important areas in the apartment are clean (bed, bathroom, fridge).
You can hear everything about what's happening in the neighbour's apartment, in the staircase or on the playground from the school around the corner.
The next train station is 15 minutes away.
