We enjoyed our tree week stay in Santiago's apartment very much. The location could not be better, in the lively Malasaña barrio with its restaurants, bars, and shops. There is a subway station right outside the small alley and another (Plaza d'España) is ideal when coming from the airport.
The apartment is well suited for a family of four and the well-equipped kitchen allows for home cooking, if one desires to do that.
Santiago was an excellent correspondent when we needed additional information.
