This is a great loft for a stay in Brussels. The loft offer all what you & your family need. The Host is really nice, friendly, flexible and easy to communicate with (quick responses). The street is quiete and not loud at all.
This area of the city is really nice and lifely with lots of restaurants, bars (Parvis de St Gilles), shops etc...few minutes away from the flat.
From there you can also make nice walking tour to the city center and touristic areas in a good 30min and come back with public transport.
