Overall this is a great place to stay at. Pretty close to the historic center. Uber and taxi's are abundant. Very safe and the host communicated very well.
Disclaimer: we stayed there on a Sunday night which was also the beginning of semana santa (national week long holiday).
I went with my family, all Mexicans who were wary of staying in an airbnb in Mexico City. They seemed to be okay with the location although I could tell they were on edge because it wasn't a typical hotel type of situation. I personally didn't feel unsafe in the airbnb itself because of the tight security, but maybe the surrounding area made me feel a little cautious. The street was pretty desolate at night around 9 pm ish so I didn't feel inclined to leave the airbnb when it was dark, not even to the oxxo that was pretty close by. I think if I had had a big group of friends with me I would've felt fine doing that.
The airbnb is pretty bare bones but it had everything we needed. Clean and neat. For the value I think it's a good choice for a short stay. David is a really great host, and responded to any questions I had right away. He was kind enough to let us check in early. I had one issue and he responded pretty quickly to it.
This is not a criticism of my stay but more of a tip to anyone else who stays here. The apt above us was occupied as well as the apt across from us. Noise traveled a lot. I could clearly hear what the people upstairs were talking about. All of the other reviews said it was tranquil and it might very well be when you don't stay during a national holiday.
Regardless of the echoing noise the place was great and I felt perfectly safe and taken care of there.
