This is a tiny little apartment but it has everything you could need: comfortable beds, a good hot shower, a kitchen with a stovetop, microwave and fridge. It even has a washing machine, although we didn't use it and a safe for your valuables. The apartment was super clean and it was dead quiet at night because the apartment faces into an interior courtyard, not the street. But the biggest bonus is the location! It is 5 minutes to walk to Reina Sofia, 8 minutes to the Prado and 12 minutes to the Thyssen Museum. The neighborhood is funky, lots of hippies and artists and cute places to eat. There is a lot of night life too, if you want it. We didn't meet Elvira because she was out of town, but she stayed in good communication with us and answered all of our questions. She was super helpful and made lots of recommendations for places to eat. Margarita took care of us while Elvira was out of town and she was also great. I would definitely recommend this place.
