Mattia is a very responsive host and all my questions were promptly answered. He greatly assisted me to get to the apartment when the taxi strike was in effect in Madrid. The apartment is very comfortable, clean and has everything you need, including a well stocked kitchen. The location is perfect in the historic core and so easy to walk to all the major sights and restaurants, with several convenient metro stops nearby. My only concern was the noise level as I am not used to apartment living. There is a restaurant across the street, an auto repair shop downstairs, a front gate that slams, and some noisy neighbors. However, it is perfect for short term stays!
