I had a great stay at Albrecht and Debora's house, they were very friendly when I ran into them. The house was clean and quiet and had all the amenities you would need, aside from a kitchen sink and stove. The room I stayed in was the large room with en-suite bathroom. The room was as described and it was warm and quiet, despite being near a major road. The room is down some stairs and so may not be suitable for those who struggle with stairs. The toilet is also up a set of stairs but the shower is en-suite to the room. The house is a 10 minute walk from the metro station and bus station which will take you to the center of Brussels in about 30 minutes. A good experience overall and I would recommend staying here :)
