I stayed in the Blue room. The place was very clean (room, bathroom, toilet, shower). The bed was very comfortable. The checkin was ok - my flight was delayed but Elena was understanding - the key keeper doesn’t speak English but he still managed to explain everything well. The room lock - which is great. I felt safe in my room. The street is very quiet, but you could hear the people going up the stairs in the building (if you come back after a full day of walking, a deep sleep will solve this problem). The place is 15 min walk to any tourist attractions. I would come back to stay in the Blue room if I come back to Madrid.
