Cristina's flat is comfortable and quiet, on a small square without traffic and within easy walking distance of many historical sights and great restaurants. Our group included two grandparents, two parents, a 2-year-old, and a baby, and we were very comfortable in the apartment. Cristina responded very quickly to all of our questions and needs, and she was willing to help out with taxis, restaurant bookings, and probably much more. One small alert: GPS does not work well in that neighborhood, so visitors (and taxi drivers!) may find it difficult to locate the building. Cristina is helpful with that problem as well.
