I had a great stay at Alberto's place. The apartment is very central, allowing us to walk to Plaza Mayor, Gran Vía, Puerta del Sol, and numerous other places within 15 minutes. The street it is located on is fairly quiet but felt quite safe. The apartment itself feels very new and modern, and all the amenities worked as advertised. Alberto provided an air mattress for my party but in all honesty the sofa was extremely large and comfortable so it was not necessary. Alberto quickly responded to all my messages and calls. Overall, I had a wonderful stay here and I would recommend it to anyone.
