Hotel Arosa is located in a large building in the heart of Madrid. The only part of the hotel Arosa at street level is the small lobby (serviced by a doorman) the actual hotel is on the upper levels, with two elevators taking you up to the different floors. The quaint elevator on the right a tiny, five-sided affair is unique, obviously having been constructed to fit the precise space available. Found on the third floor is a pleasant reception, lobby, and restaurant area whose decorative style could be called intense: Pseudo-French with antique accents.

Hotel Arosa is spacious, attractive, and comfortable, and a veritable oasis in the heart of the noisy town. The bedrooms, each different in shape and size, are individually decorated. Some have a modern feel while others (such as 509, a pretty corner room with sprigged floral design on the walls) have a more traditional ambiance.
