I went to Brussels as part of a group business trip. It wasn't anything really special. It was tidy and secure (doors are locked after 11pm but there is always someone on duty to open). Sleep quality is good as the hotel is virtually silent at night, if anything WE were the noisier ones!
It was a bit of a shock to realize that the hotel was in the middle of Brussels' red light district though. It is a good enough hotel but not in the nicest of areas though. Short distance from Brussels-Midi and the European Parliament precincts on the Metro too if that's what you're after.
