DO NOT BOOK WITH THIS HOST!
Diego is a scammer, already reported to Airbnb. I did the reservation and, by the time I got to the adress, the host was not there to meet us, did not answer my calls and texts, never heard from him again.
Airbnb support could only get solution for me the following morning. Had to find an hotel as a substitute for this mess.
Airbnb already refunded me the money I spent on the reservation, but an extra compensation is more than due, considering this TERRIBLE experience (the worst ever).
Search for other stays in Madrid, skip this one! THIS IS SCAM!
