I experienced Sam as a very gentle and supporting host. We had very good communication, everything worked fine, flexible and quick. The appartment is very nice and well equipped. One annotation: The second room is quite cosy and you reach it only by crossing the large bedroom.
You can find lots of information about a stay in Brussels in the appartment or just ask Sam. He showed us a wonderful local restaurant in the neighborhood.
I can definitely recommend a stay at Sam's appartment.
