We ended up with a last-minute need for two hotel rooms for five people, and Hotel Princesa was perfect. The rooms were quiet, comfortable, and well-designed, the bar and front desk staff were friendly, and they were willing to store 10 (!) bags for several hours before we were able to check in. The showers were amazing, beautiful view of sunrise over Madrid, and a convenient location, about a 12-minute walk from Plaza de España.
