Adolfo's apartment was conveniently located a few short blocks walking distance from the Atocha train station. The unit was as advertised. Adolfo was easy to communicate with, and he coordinated our arrival with his housekeeper, who met us and provided the keys. She didn't speak English, so communication was difficult with her, but we figured things out.
Only downside was the apt is on the 4th floor and there was no elevator. We had to carry our bags up the stairs, which may be a limitation for anyone with a physical handicap.
