My 2 sisters and I stayed in Emmanuel's apartment for 2 nights and felt completely at home. Emmanuel was very helpful and attentive and was just downstairs if we needed anything. He also gave us plenty of suggestions about where to eat in the area.
The neighbourhood was nice, with a supermarket just around the corner. It took a little while to get into town but we didn't mind at all. The flat itself was cool, super comfortable and had everything thing we needed. As others have mentioned there are some stairs to get up but that was no problem for us.
All in all we had a really great time and would gladly stay again on our next trip to Brussels!
