Abigail's place in Coyoacán is excellent! A cozy little apartment in a complex in the Del Carmen colonia, it's in a very safe and peaceful part of CDMX, that nonetheless is walking distance to some cool stuff: a cool local market, parks, museums, restaurants etc. Highly recommended area to stay, although a bit of a hike (Uber or public transit) to the central part of the city. (The other side of that coin is that, after hanging out in the chaos of CDMX all day, it's nice to come "home" to somewhere peaceful.)
The place itself was great: comfortable, quiet and well-appointed. The rooftop patio is a nice place to have your morning coffee. What was particularly excellent about this place was Abigail's communications: she responded to questions very quickly and offered help where it was useful.
We wouldn't hesitate to stay there again. Recommended!
