Andres' apartment was great and we thoroughly enjoyed staying there. The check-in and comms were perfect and Andres even made sure we were ok during our stay. The apartment is centrally located, near a major train station and metro. Some of the key sites of Madrid are within walking distance as well as a number of shops, bars and parks. Despite the central location the area is quiet and there is no traffic or people noise.
The apartment itself is very comfortable with everything you'd expect in there. Would stay again.
