I had a nice stay at Le Châtelain overall. The hotel is clean and comfortable, and the staff were generally friendly. The room was fine, but quite dated. It was more like a 4 star standard than a 5 star.
Location wise, it’s a little away from the main areas, but still decent if you don’t mind a short trip to get around Brussels.
Nothing major to complain about, but also nothing that really stood out as amazing. A nice place to stay, just don’t expect full luxury.
