I highly recommend staying at Santiago's apartment! The location is fantastic. It is centrally located and we were able to walk to all the sights in the city. There are amazing restaurants within a few blocks, but the street is quiet and beautiful. The apartment itself was extremely clean with all amenities, and Santiago even kindly provided coffee pods for the nespresso machine. My favorite part was the cute balcony overlooking the street! Santiago was an excellent host, who was easy to get in touch with, and provided helpful maps and information for our trip. I will definitely stay here again if I return to Madrid! Thanks Santiago!
