I highly recommend this place if you are looking for a quiet place that is still convenient to the City Center by transit. Joaquin is very friendly and replies quickly to all messages. His place is very clean and comfortable.
Location is quiet and only 1 minute walk to La Almudena metro station on the 2 line which takes you directly to the major sites downtown in about 10 minutes.
There is a grocery store next to the apartment building.
Free street parking is abundant during the day, but can be full in the evenings when when we had to circle around to find a spot. But next morning, there were plenty of spaces.
