Apartment is clean and spacious with nice access to the central courtyard for a morning coffee. There is no noise from traffic or pedestrians and Luis leaves some water and coffee in the apartment so you can at least make coffee without needing to make a trip to the grocery, which is nice. The doorman is there 7x24 and there seem to be maintenance and cleaning personnel present during the day. If you have any concerns on safety I could not imagine feeling safer in CDMX. Polanco is a pretty upscale neighborhood and I felt comfortable walking back to the apartment even at night. It seems there are only local neighbors in the area. There are many bars and restaurants in the neighborhood and a nice park for a morning run.
