The apartment has a very good location—10 minutes from the Grand Place, and very close to a metro station. Two supermarkets are available within meters. The space is clean and facilities as are expected. If you need darkness to sleep, bring a mask as there are no blinds.
As someone else already wrote, maybe the pics are a little bit too good and the description oversells a bit the place. It is absolutely OK, but I would not call it "superbe".
