Apartment is in a great location and both clean and safe. Communication with Sofia was very easy, though never got to meet her in person. The security/doormen downstairs are great and the neighborhood feels very safe at night. Walking distance to a number of great restaurants and bars and amazing street food stands right outside/around the corner from the apartment. Consistent with other reviewers, the apartment (3rd floor) is quite loud as it faces Calle Salamanca which is a main street with a lot of traffic. However, the provided ear plugs were helpful and given we were up early and out until quite late every night, it wasn't a major issue.
