Paco & Maria were warm and welcoming hosts and greeted us on arrival with a map, some excellent advice about local eateries, getting around, and a cell phone to borrow. They both are busy working people and they live on the top floor of the house so we never bumped into them again, except when sweet Maria came to say good bye. We enjoyed the abundant continental breakfasts in the huge kitchen/dining room, which is a common area shared with the other guests. Over coffee, tea, yogurt, fruit, cereal and toast it was fun to chat with the other guests before taking our daily excursions. The house itself is lovely, large and clean. We really liked the third floor room, reached via an outside spiral iron staircase. There are two super cute dogs--one a huge, sweet, cuddly St. Bernard, the other an independent moppy haired Yorkie who has a fondness for the dried magnolia leaves that fall from the tree in the front of the house. If you depend on Internet for work or correspondence, the best place to get it is in the shared common area on the second floor of the house. Paco explained that the brick walls are the reason the Internet is a bit finicky in the bedrooms. The neighborhood is conveniently located to Chapultapec Park as described. As runners, we enjoyed running there every day--a 5 or 6 minute jog from the house. The metro system is super easy to use, though take a map with you to find it the first time if you're walking. Paco can arrange for his driver to take you places for a reasonable charge, and they also recommend taxi drivers--which is a good idea in Mexico City if you're going any distance.
