I was in Madrid for one night, and upon my arrival Nacho was patiently waiting for me outside the entrance to the building. He graciously assisted me with my bags, and showed me to my room, and around the apartment. It is a small room with a single bed suitable for a night's stay. Tea and croissants were available for breakfast. The bus stop is 2 mins away and the apartment is close to Atocha Renfe.
