Had a good stay here. Very basic but comfortable, quiet, clean, great location in Madrid, and great communication with Cristina and Diana. The room is small and no frills, with only two very small windows that don't let in much light. And as another comment noted, you only have access to part of the dresser, so more space would be nice. But the bed is high quality and very comfortable (like, one of the nicest Airbnb beds I've slept in!) and the room faces the back of the building so, despite the lively neighbourhood, it's dead quiet at night - perfect for a good night's sleep. You share the apartment with three other travellers, but I didn't see the other guests that much and there is a good level of privacy. Great communication with Cristina, who doesn't live there, and Diana, the caretaker, who lives in the next building over. There is no common area/living room and the kitchen is pretty small and basic. But if you just need a good room to sleep and relax in, this place is a really good value. Also, wifi is really good and you can use the washing machine. Muchas gracias Cristina! :)
