This place is fantastically located, right by a beautiful park and in a great neighborhood. It's within walking distance to multiple restaurants, cafes/coffee shops, convenience stores, and a metro station. There is no AC, but Cuauhtemoc provided a fan which was enough for us since it never got too hot during our stay. The bathroom is nice, kitchen includes a small fridge/oven/sink, and there are two bedrooms (both provided with mosquito nets). The walk up to the apartment is great with tons of plants and colors. We just brought carry-ons and personal items, so we had no trouble getting to the room but the stairs can be a little narrow (although we had no problems). There is no TV, but WiFi is there so bring a smartphone or laptop if you want to stay updated on news or TV shows. We walked to most places and used Uber (really cheap compared to US prices, most expensive was below $7), but CDMX has tons of different ways to get around (taxi, bus, subway, and bikes) available, especially if you have a good handle on Spanish.
Communication with the host, Cuauhtemoc, was easy, and we received fast responses to any questions or concerns. The WiFi did go down at one point, and he provided with a password to another and had the problem fixed relatively soon. If you're on the fence, I say go ahead and rent this place!
