The house is in a fantastic location, on a charming, lively street near the center of Brussels. And it's a great size for a group. We had two families stay and were comfortable. Haleh is a great host and very responsive. We had one request and she acted on it immediately. Two notes:
First, the street outside is full of cafes and can be boisterous (the World Cup might have accentuated this), and the front rooms are right above the street. But the back rooms are much quieter, for any light sleepers.
Second, it's a tall, narrow house, and the upper bedrooms can get warm by the evening when it's hot outside. Haleh was super responsive on this and helped us find a solution quickly.
We had a great time in the house and would recommend it.
