AirBnB has a consistency problem -- the properties vary tremendously in terms of quality. I think the "superhost" concept has fixed this. This is the second or third time I've stated with a superhost and they've all been exceptional.
Cristina's place is in a nice, central location, as long as you understand that you're outside of the Roma-Condesa-Polanco tourist area up north and will need some kind of transportation -- Metro or taxi or Uber -- to get to most of the big museums. It's walking distance from the center of Coyoacon, which is the most interesting part of Mexico City, as far as I am concerned. It is also walkikng distance from CEPE, if you're a student there, and there is a Walmart and Starbucks nearby.
Nice kitchen and essentials for cooking. Balcony. Cristina is super-responsive. She checked in on me several times, and when I was cold she immediately found me a blanket and incredibly thick quilt. I didn't want to get out of bed. Cristina also drove me to school after letting me in when I came over with my bags a few hours early.
I would stay here again and would recommend it to anyone.
