We were warmly welcomed at the apartment by Severine, who speaks excellent English (and French). The apartment is large and comfortable, and has a relatively quiet location on a semi-pedestrian street. It is located within easy walking distance to sites such as the Plaza Major, Mercado de San Miguel and Palacio Real, but further from the museums and Parque de Buen Retiro. The location is good for walking and near many shops and restaurants, including a very good one - Taberna - right across the street. The apartment was clean and well-appointed. We would definitely recommend staying here.
