Isabel's flat is in an ideal location for experiencing all of central Madrid. Very walkable and also very close to many Metro stops. Isabel was very easy to communicate with both before and during my stay. She was also very flexible with my arrival and departure times which was very helpful. I stayed alone and felt very safe in this residential area. The bedroom does face the street which means some noise in the evenings, but it didn't bother me. Otherwise, the flat is flooded with great natural light - just like the pictures. The bed is very comfortable! A wonderful stay!
