We had a wonderful stay at Antonio's place. It was our first trip to Mexico City and Antonio was a responsive, friendly and helpful host. We happened to be in Mexico City during the tail end of their water crisis (no running water in the city for a whole week) and Antonio was communicative throughout the process (providing water jugs for use in the kitchen/bathroom). The studio is located in a charming and walkable neighborhood, and although we didn't need it, a cell phone was available for our use during our stay.
