Nice flat. The location is ideal : 15min walk from the Brussel Midi train station, and 5min away from the "Grand Place" of the city.
An additional blanket would have been appreciated, fortunately the heater works just fine.
It is a studio, with the sofa-bed being right behind the entrance door. You can easily hear people in the corridors.
On the other hand, the sofa is quite comfortable despite not being a real bed.
