We loved this apartment! It was very centrally located but on a very quiet side street. Perfectly situated near 3 different metro stations so getting around was very easy either walking or taking the metro. The check in process and keyless entry was extremely easy to use and very hassle free! The apartment was the perfect size and very clean. The hosts were extremely responsive and always got back to us with any questions or recommendations in just a few minutes!! It was hard to believe this apartment was in the heart of the city because it was so quiet inside the apartment. Would love to rent this exact unit if we return to Madrid!
