I stayed here for a day during a trip through Europe. It is by far my favorite hotel I have stayed in thus far. Stayed up in Room 7, which had its own little balcony to go out and sit on, which offered stunning views of the bell tower of the nearby cathedral. The hotel is a nice blend of modern styling and accents on a classic older building. The bathroom in the room was excellent and the space was well laid out with plenty of storage space and sitting room. Loved the exposed beams in the ceiling. In order to be totally objective, the only nit I would point out is that the old wood floors in the hallways squeaked and creaked a lot so foot traffic near your door was definitely audible in the room. Notwithstanding, I wouldn't even consider staying somewhere else in Antwerp.
Prós: Incredibly charming room; excellent guest services; great location
