The apparent is very nice and large. It has very nice furniture, and the large window creates a nice athmosphere. The location is good, in the center of Brussels!
However, there are a few points that need to be taken care of by the owner (I've send this also to the Airbnb contact).
Both of the showers malfunctioned, and should be repaired for the next guests arrive. You could also improve by replacing the mattresses, they are getting quite thin and for us not too comfortable. I would also be nice to check cutlery, and to add some more glasses and (small) plates.
We had a good stay, in a nice place, but the apartment can easily be improved to make it better!
