Mario's place is convenient and central to many spots in Madrid. The room I had faced the very busy plaza and the windows do not close completely. So it was very loud at night. The mattress on the lower bunk was very uncomfortable. Overall the location is great, the host is VERY communicative and checked in on me during the stay. One bathroom does not have a lock and the door has difficulty closing. This did not pose any issues but important for some people to know. The posting states breakfast is included, but tea and coffee are the only items offered and I would not constitute that as breakfast- also important to clarify. The spaces are clean with some wear. There was a key for each room and I felt safe walking around the neighborhood. Overall, a good place to stay with minor considerations for improvement.
