We had a very good stay at Carlos's place. The unit itself is cute and the location is perfect for exploring Coyoacan, a neighborhood we quickly fell in love with, as well as a relatively quick taxi ride to other parts of the city and the airport. Carlos also provided a nice guide for spots to check out nearby. We did have a little trouble communicating (Carlos asked us to reach his mother for access to the unit, who very kind but not immediately responsive) and the hot water was iffy. Neither of these seriously impacted our stay but worth noting, especially if you love your hot showers.
