I liked this place. The location is very close to the main tourist points and subways stations! Marvin was a nice host, the apartament was clean and the bed is comfortable.
PS: Calle Fuencarral has life 24h per day, everyday. So if you have problems to sleep with noises, maybe you will not be like and be frustated.
The only point that I don't liked: the wash machine in the apartament was not working, and I choose this place mainly for this availability.
