We had a wonderful time at Margarita's apartment and everything was exactly as described. We didn't have a chance to meet Margarita but her sister Mariel met with us for the keys and she was extremely kind and accomodated a quite late check-in as our plane was delayed. The apartment is very clean and big enough and very close to a couple of big supermarkets. Thank you Margarita and Mariel for a great stay in Madrid!
