Stayed for 2 weeks and found the place significantly lacking in quality control...
In general, I do't recommend any places that are A) shared with other guests (especially with instant booking, because it's like Russian roulette), and B) where you never meet the host in person, or the host is not the owner.
This place has 6 or more rooms that are being rented to apparently anyone, where you get to share your bath with some of them, and never get to meet anybody formally, including the host.
Regrettably neither the bath nor the other guests were suitable for proper use and accommodation. Neither was the host suitably aware of the professional requirements for running a place such as one with 6+ independent rooms. There were further issues with accessing the place since it was deemed necessary to only provide 3 of the 4 keys required to get to my room. Very annoying, especially when the doorbell was not properly working. The room was also without any heating, and in the middle of winter in CDMX this does not make for a comfortable nights.
