The apartment is spacious clean and fresh located in a charming pedestrian street within 100 meters access to a street where you can get a taxi. Unfortunately we changed out travel plans at the last minute and only stayed in Fernando's apartment for one night so we could not explore Madrid as extensively as we wanted.
Fernando was out of town but he was in permanent touch with us making sure everything went fine. The person he left in charge was very helpful. I would definitely stay in this apartment next time I go to Madrid, it seems to be a great place for a longer stay.
