Highly recommended for a trip to Madrid. Superb value for money, and an excellent location right next to Embajadores metro station and within an easy walk of Retiro park, Atocha station and the Rastro Sunday street market. Best of all was the thoughtful host, Fernando, who couldn't have been more generous with his time in suggesting places to visit, helping with all sorts of tourist practicalities, and providing breakfast and picnic snacks. I will be planning a repeat visit.
