What an amazing stay! It's even better than the listing suggests.
Francisco was great about answering questions and offering help before we arrived. He arranged for his excellent driver, Gabriel, to handle airport transportation, as well as take us to the pyramids at Teotihuacan. And when we arrived, Francisco sat down with us and a map, and gave us detailed directions and advice on how to spend our time in Mexico City.
And the place is incredible. It's situated on a quiet side street, facing a private courtyard (you share it and, occasionally, the kitchen with Francisco's lovely family, who live in an adjacent apartment, but were gone most of the time we were there). It's three stories, has been creatively renovated by Francisco himself, and includes a couple of spiral staircases, great decor, and a third-floor deck that I already miss. As a family of four, we didn't even use the second floor rooms. The two dogs are wonderful; even my wife, who's not exactly a dog person, got attached to Cupito and Maya.
Oh, and daily maid service is included (which I don't believe the listing states).
We loved Mexico City and wish we'd stayed longer. If we go back--and we certainly hope so--we'd love to stay at Francisco's place again.
