Alfonso is the absolute best host. Even though there was a building issue at one point with one of the showers (through no fault of his own), Alfonso was on top of communication with us (both Spanish and English), and even worked around my insane work schedule to make time to come take a look at the unit while my husband was home. Since we were also looking for apartments (having just relocated from the US to Madrid), Alfonso connected us with several people who were renting, and in addition to hosting us in his beautiful flat, helped us find a place to live! He had an abundance of local recommendations on food, neighborhoods, and things to do, and even took the time to grab a beer with us down the street with his daughter. The building is secure, located close to EVERYTHING, and the apartment itself is spotless, and well-equipped with cooking utensils, and ample common space. Quiet street, but just a block over from wonderful places to eat and fun nightlife (if you're looking for it). Nothing could possibly have been better - even with two working showers!
