Enrique's apartment is in a very well-maintained, quiet, high-end apartment building just a few minutes walk from Atocha train station and right next to the metro. It has a lovely balcony overlooking a quiet large courtyard and was sparkling clean when we arrived. In fact we (including our 1-year-old son) needed a place on a moment's notice late at night and Enrique replied to our request immediately and let us into the apartment. We had a great stay. Highly recommended.
