Albrecht and Debora's house is beautiful and the rooms (bed & bathroom) were spotlessly clean. While the room is not located in the absolute centre of Brussels, it is very well connected with metro and tram which take no less than 10 min to the most central parts.
Albrecht and Debora were very helpful in answering any of my questions. They also offered sweets in the room and provided a fen, which was highly appreciated as the room gets rather warm in summer as it is under the roof.
I enjoyed my stay and would highly recommend staying at their place.
