I felt at home in Francisco and Maria´s house. They made it possible because they trust their guests. This is something that I really admired. The house is very very clean and the crew members are incredibly careful and sympathetic, as well as the hosts themselves.
The neighborhood is good and close to many museums and some restaurants. It is not that far from downtown. Metro might be an option, but do not depend on it during the rush hours. The hosts borrowed me a bike card with which I could use the Mexico city bike system and ride to many tourist spots.
