We spent a week at Carmen's apartment and found it to be absolutely perfect! For visiting the three major art museums (Prado, Reina Sofia & Thyssen-Bornemisza), it was the ideal location with both train and subway transit also within easy reach. Having a Carrefour express within a minute's walk was very helpful for our family as well. The apartment is lovely, spacious and well-equipped but what truly made this rental special was the service; communication was prompt and thoughtful throughout the entire process. Thank you, Carmen and Diego for making our first trip to Spain so memorable. We hope to visit again.
