Antoine's place was so great! The location and cleanliness are the top draws to his place, as well as the very reasonable price. The flat was surprisingly quiet, despite being so close to all of the activity in Brussels.
We did have a bit of trouble finding the place where we were to pick up keys (the street names change almost every block), but when we found it Antoine's assistant gave us the keys, made some excellent food and chocolate recommendations, and walked us to the flat to show us around.
And Antoine was always prompt in responding to any questions we had. I can't imagine a better place to stay while enjoying brussels.
