This is a neat space and base for your stay in Mexico City. The location is a big positive, a couple blocks from the Metrobus stop, 10min walk to the nearest subway. The neighborhood San Rafael is humble and safe while still being close to Roma Norte and the amenities of supermarket, great restaurants, laundry etc nearby.
The apartment is old so some systems are outdated - gas system is shared with neighbors and took over a day to refill, for example. The shower is not current style drainage so you have to be out quickly before it accumulates. These are the little things to expect. The host Raul is attentive and does quickly whatever is in his control (gas and internet entities in the city take longer).
Hot water works fine, as does the big screen TV and Roku Netflix etc system a nice modern touch. Internet is mostly functional at 10-15mbps. As the host mentions no noise allowed, although there’s no problems playing music just thin walls for the family next door.
It is on the 5th floor so you must like stairs.
Overall a good experience and pad enough space for 1 person or a couple.
