We didn't meet Etienne directly, but his daughter welcomed us in the house. Instructions were clear.
It was easy to find, the place is nice and cosy, quiet, comfortable.
The room is big and the bed comfortable; the bathroom is great. Clean towels were provided which is always practical.
The location is quite convenient if you are not afraid to walk for a few minutes to the metro, which should take 10-15 min to reach the center of Brussels.
Overall, we would really recommend Etienne's place.
