This is a great value in a quiet neighborhood that is walking distance to the grand palace area (with pedestrian only streets) with tons of restaurants around and shops as well as antique stores and art galleries. Also walking distance to Sablon area with the Brussels palace and other government / posh areas to walk around. Very close to the Ferris wheel too for some great views. If you are traveling by train, the Brussels-MIDI station is closer than Centraal (about 15-20 min walk or 5 min Uber).
The room is on the fifth floor but stairs are better than Amsterdam and the top floor is way bigger than cramped Dutch apartments. The room has a double twin bed (side by side), couch, small table, and basic supplies in the kitchen. No tv and Wifi is a bit slow on the top floor but generally you will likely be out exploring and not sitting in the room all day. The best part is the view: one small balcony looking south /west and a huge balcony facing north / west with seating on both sides. Perfect place to drink some wine after a long day or start your day with a breakfast. Recommend a little bakery / sandwich shop just around the corner to the left called Moisette.
Overall would stay again. The host is great and has a few other properties around.
