We booked for 5 nights and very much enjoyed our stay. The house is lovely and situated in a very walkable neighborhood not too far from Chapultepec Park. Paco and Maria were gracious hosts and incredibly helpful with suggestions of things to see, which taxi service to use and restaurants to enjoy. They can also arrange for a private driver to take you to various sites around the city and to/from the airport - the driver is very friendly and expertly navigates Mexico city traffic.
