Helen was very friendly and helpful. She met us at a restaurant that she had recommended- which was very good by the way. She walked us to the apartment and showed us how things worked. When we had a few questions she responded very quickly. She was a pleasure to work with! The space was small but clean and comfortable, and had everything we needed. The location was indeed very central, quite near the Plaza Mayor and walking distance to the museums, though we took cabs, being lazy in the heat. There were restaurants and shops downstairs and nearby. And the map of recommended restaurants was helpful.
