We loved Margarita's apartment. We'd start each morning with the windows open, listening to the fountain in the square. The apartment is in a beautiful neighborhood (extremely easy to walk or cab to most tourist attractions), felt extremely safe, and was thoughtfully decorated. We enjoyed our time immensely. Margarita's friend, Rafael, waited up for us and made sure to tell us about the best restaurants. The one thing I'd note is that, because the apartment faces the square, it is fairly bright at night (an eye mask might be a good idea). But we couldn't have asked for a better apartment or experience!
