We really enjoyed our stay in Polanco, the neighborhood was safe and the underground parking was secure and easy to find.
A few minor things - the apartment was poorly ventilated and was a little bit musty, specifically the bathrooms & living room couch. I would recommend bringing a small light up hand mirror as the lighting in the apartment is dim, making it difficult to put on makeup.
Overall, it was a wonderful & spacious space to stay. Ma was a good host and responded quickly. Additionally, there were no check out cleaning requirements which made check out a breeze.
