We enjoyed our time at Antonio's flat. He is a great host and was very helpful, from suggesting places to visit in Madrid to booking taxis to the airport for us. The apartment's location was ideal for us. As runners, we enjoyed the easy access to trails in El Retiro. It was fun to be part of the Madrid running culture. The apartment is also in a quiet area. Access to the more touristy areas is easy via Metro, which is a fairly easy system to navigate. We recommend Antonio's apartment. We would definitely stay there again.
