Everything about Juan's apartment was superb: the location (on a cozy, quiet street with cafes and shops, and a short walk to the Real Madrid Museum) the comfort (large common area for all of us to relax, really comfortable beds, fully equipped kitchen and wonderful bathrooms and showers) and the style. We liked it so much we talked about what life would be like if WE owned the apartment. A large grocery store was just a short walk away, as well as a couple of metro stops. We took the train from Madrid to Barcelona and we could walk to the train station from the apartment. We ate almost every meal in the neighborhood. Try the tapas, especially the tuna tartare, at Cafe Barbieri.
The check-in process was smooth. Marta was friendly and lovely, and she was waiting for us at the apartment. I can't think of one way our experience could have been improved!
