Very nice, bright place in a good neighbourhood. I stayed at Alexandre's place over summer, and find it great fit for me - it met all my expectations. Top floor, huge windows, bathtub with glass wall were most attractive parts.
I didn't have to worry about bringing linen, towels etc as Alexandre took care of anything. He also prepared a list with useful information in advance. Place was fully equipped. Most importantly Alexandre was very responsive all the time, even when he was overseas. I was happy with such a host :)
Area is peaceful and not far from center. Close to Flagey: plenty of cafes, market on weekend, and beautiful lakes with swans to make a jog around.
I had a car, and it was problematic sometimes to find a parking space nearby (there is no parking lot). As a consequence of top floor, I needed to bring my luggage up and down four level each time (as in all typical belgian houses there is no lift).
Overall I really enjoyed summer in Brussels and was lucky to find such cozy place for a stay.
