Pros:
Excellent location in a fantastic part of Brussels. Everything you could want in the city is only a walk or short metro ride away. The staff is excellent and exceptionally responsive. Very good hosts.
Cons:
It is quite loud throughout all hours of the night due to the great location right above grand place, and the bed is not the most comfortable with two people as it is a pullout.
Overall:
Loudness aside, would still recommend this location to anyone. Good place and great location.
