This was my second full-month stay (summer and winter) and I've already booked my third.
Great value for Brussels, particularly for cyclists. Warm in winter and cool in summer, and the terrace is lovely on a sunny day, even in February, and very quiet at night. Benedicte was exceptionally helpful with off-schedule check-in/out.
Everything is as good as (or better than) described but this may not be for everyone, as it is relatively far from the city center (but only 15 minutes from nearby subway station, or 20 minutes by bicycle), and up three flights of stairs (but I'm 64 and had no problem climbing them).
