Good location- next to Mayo Plaza. Alberto deserves to be a super host because of his communication skill, check in/out process, cleanness, his attitude, and extra touches such as welcome food as well as written instruction of sites to visit and free museum info. Of course, he will go over everything when you arrive. His place was as shown in pictures- small but cozy and cute. I enjoyed his attic a lot. I recommend his place if you are visiting Madrid, but remember his place is on the 4th floor with no elevator which Alberto described as "free gym". I considered it as "working out" whenever I went upstairs, so it was not an issue for me.
