My girlfriend and I stayed in Thibault's place for 4 days at the beginning of July, and enjoyed our time there quite a bit.

The apartment is great: open, well-furnished, sunny, and comfortable. The roof-top porch has an excellent view and we enjoyed many nights out there, eating dinner and drinking some tasty beers. The kitchen is big and more than functional, so we were able to cook several satisfying meals. Because it is on the top floor and has many windows on both sides, there is a nice cross-breeze, especially at night, when it is useful to cool down the apartment (which didn't get too hot during the day, either, despite the heat-wave Brussels went through while we were there).

The location of the apartment was convenient for our needs: it is really close to my favorite brewery, Cantillon, and close to the Midi train station. There are several small grocers in the area, as well as some cafes, none of which is too expensive. Perhaps the only downside about the location is that the area around Midi can feel a bit rough at times, but we didn't have to work that hard to avoid the worst of it and generally had no problems.

All in all, we had a great experience and we would happily recommend it to most people (especially if you plan to spend significant time at Cantillon).
