I stayed one day in the room (which is more like a private room in a hostel) but regretted for not having stayed more. The room is very good (spacious, clean, with a good bed, having many outlets), it is located in one of the best neighbourhoods of CDMX, the kitchen was well equipped, and the (shared) bathroom was also clean. It was above our expectations and we definitely recommend it.
The only issue we had problems was to checkin. As we got in front of the building we simply did not know what to do, we had no instructions at all. So we had to look for a place with internet, open the computer and contact them with the hope that they would be online so they could give us the instructions. Once we contacted them via AirBnb, they answered quickly and gave us the code to get in.
