I had a very comfortable 3 night stay at The Scott hotel and would recommend it to anyone visiting Brussels. The hotel was located in a quiet residential area, but only a short walk to transport, shopping and dining options.
The room was very spacious and the beds are King (not queen) sized. Things I wish the hotel would provide/improve on are: a mini fridge, keycard requirement for elevator use (greater security), and control over the underfloor heating–the room was always so hot because of this.
