Alberto was a wonderful host, friendly and informative of Madrid and the surrounding area.
His studio is very clean, and had everything I needed for a comfortable and restful night's rest.
Alberto provided clear instructions on how to find his residence and was always quick to respond. He probably had the fastest WiFi I've come across in Spain thus far, and I've been here close to 3 months!
I would recommend staying with Alberto if you are ever in Madrid.
