Jean was a good host, we got in very late and he was able to accommodate us even though it was later than the check-in time. He also stored our suitcases while we tour the city. We didn't spend much time there, we just slept that night and left in the morning, but the apartment is very nice, well kept, and the best thing is the location, right of the metro line and steps from the Grand Place.
Only thing I will complain is the bed, it makes a lot of noise, you barely can move, and is not sturdy at all. Other than that, it was great.
