We spent only one night in Brussels but had a great time. The location right next to the Brussels-Midi train station and the ryanair coach stop to Charleroi airport was ideal for our quick stay. It's about a 15-20 minute walk to the central square.
Francesco was a welcoming host and the room was clean with a small kitchen attached. Bathroom/shower worked fine and the kitchen was well equipped. The room was packed with beds (a bunk bed, 1 single and one double) which was ideal for our party of 4 friends, although it left little space for anything else (which wasn't an issue for us as we spent hardly any time in the flat).

Overall, great for a short stay for a group of friends.
