We had an extended stay at Ana's and Eduardo's place; they are great hosts! Except for a couple of times at the beginning of our stay, we didn't have the need to contact them because the places was prepared. They were quick to respond.
Great location for exploring Coyoácan and surrounding areas. Nice park nearby for walking/running. Running errands is convenient with Walmart Express, Walmart Supermercado, as well as local markets. Metro, metrobus, trolebus are within walking distance (get your steps in!)
Overall, a wonderful experience!
