AC Santo Mauro
Zurbano, 36, Chamberí
Spread out over three elegant buildings that used to serve as the home of the Duke of Santo Mauro, this recently renovated boutique hotel is a love letter to the decadence and splendor of old Madrid. Inside, the former ballroom has been turned into a sweeping lobby and the library became La Biblioteca Restaurant, where you'll find an excellent menu of traditional Spanish cuisine. Meanwhile, the spacious guestrooms are done in comforting earth tones for maximum relaxation.
