Very welcoming and nice mother and son! Close to the metro station Antonio Machado (2 min walk).
Small room but very convenient and with all the essentials needed.
Would not however recommend to people who don't want to feel part of the family as the apartment is quite small (can hear the TV in the evening for example and sharing the bathroom with the hosts so a few hair here and there but nothing terrible). Also, they don't speak English so bring your Google translate.
Very good value for money overall!
