This place is in a great location close to El Retiro park, Metro/Train Atocha station, Prado and Reina Sofia museums, and a number of restaurants. The mattress is comfortable and room is clean. Check-in is smooth and easy with great instructions.
One thing was that the night club nearby played musics from 12 am to 5 am during our stays of 2 nights. We could not sleep during that period of time. The music sounded a lot louder during that time of day if you are not deep sleepers.
