A great place to stay. The studio is incredibly nice - clean, pretty and convenient. There is a small "garden" in front of it. You have to be aware that it's the part of the host's home, which in my opinion is nice, but during our stay, nobody really lived in the house. It can be cold sometimes in the studio, especially in the mornings, but the hosts provided us with an electric heater and everything was fine (we spent here a month). The hosts are super communicative and helpful in general, so that's a big plus as well. Internet also works pretty fine, we managed to have stable calls with people from Europe.
The area is also very nice, but beware that it is pretty expensive. If you buy stuff in Walmart and eat tacos in small, private places, it will be fine but restaurants & some more "premium shops" like eco stuff are very expensive in this area. A big plus is that area seems very safe, so if that's your main consideration in CDMX, it is a great choice!
