Mario was a pleasure to deal with from start to finish. Genuinely felt as though Mario wanted us to have a wonderful stay in beautiful Madrid, and we did. The apartment was amazing, a piece of history and beautifullly decorated, with all the modern conveniences you could hope for. If you are seeking to stay close to Plaza Mayor, I think this would be the place for you. Everywhere is convenient and walking distance. We felt at home. Thanks again Mario for making this a wonderful trip.
