Low costs, especially practical for a short-stay a couple of days. Dominique give's you good inside-tipps for Brüssel (where to eat etc.).
You have to climb some stairs to his appartement (your room is within his appartement with a common shared bathroom) and to eat out, but that was fine with me (he also has this mentioned in his house rules).
Also to say is that Dominique made it possible that I could bring my bags into his appartment even before the usual check-in-time, which was very nice.
