I stayed in Ana Paula's apartment for about three weeks and had a great experience.
Overall: The space was cute, functional, well-located, and met all of my basic needs. Ana Paula was a responsive and communicative host.
Bathroom: The shower was a highlight--it felt luxurious.
Kitchen: The kitchen was small and bare-bones, so I did not cook much during my stay. This was not an issue for me as eating out in CDMX is very affordable (often cheaper than buying groceries and preparing your own meals).
Noise: Because other reviewers have mentioned that the apartment is loud, I'll note that I did not have any issue with noise. The apartment is on the ground floor of a building located on a quiet street, and I sometimes heard other guests entering or leaving, or music from a nearby bar on weekend nights. Aside from that, I found the apartment to be quiet and peaceful.
