Super great location and nice outdoor patio. It is a walk-up, and the room at the top is a long walk up, so be careful if you have a ton of luggage or don't like climbing stairs.
I can think of a better spot to be in Brussels. Great restaurants nearby.
The unit was undergoing some construction, so there was drywall in the hallway, and we had to request workers not be there during the day. Also, water pressure is a little low at the very top bedroom. Overall a good stay.
