I've stayed at a number of Airbnb's in Canada and Mexico, Everardo & Fidias are among the best hosts I've had. Very courteous and concerned, and very responsive. Great hosts!
The casita is cute, and super clean! It is small and efficient, great for one or two, but you would have to be very close friends with much more than that. Location is great! 10 minutes walk to Metro and 3 minutes to Metrobus. The neighbourhood is clean, and you are but a few minutes walk to a couple of lovely parks, dozens of fondas with good food, the local Mercado, bakeries, barber shops, laundry.....everything one needs for day to day life. (I was in CDMX for 3 months, living the life as a local, not as a tourist.)
The downsides: it's like living in a kennel. I've never experienced so many barking dogs, almost endless throughout the day. Thankfully it is quieter usually between 11pm and 7am or so. The other noise issue: this apartment is one of three in the same building. If you are unfortunate enough, as I was, to have guest in the rear unit, they may have little (or no) regard for others, so they make a LOT of noise. I put it down to ignorance and inconsideration for others, beyond control of the hosts. Lastly, it's probably a good idea to have a good data plan for your wireless devices, as the WiFi here is poor. It's shared between the three apartments, and if others are using bandwidth, you may have issues.
