Eloy was perfectly responsive + friendly + accommodating. The flat itself is very much as-advertised/it appears in photos. It's a modern-chic unit in a modern-chic newer building with a proper lobby staffed with blue-blazered professional hospitality/security staff. The location is right on the main drag in Polanco, but it was notably quiet overnight. Polanco itself is by most all accounts the most "sanitized" neighborhood in CDMX. Those seeking a super-secure feeling in an upscale zone with minimal culture-shock value will be well-served by a stay here. Very temperature-stable as well.
The unit is in good condition. The only points of concern/potential improvement were: 1). Power outlets in the living area are minimal/not ideally located...but were adequate overall in the unit as a whole. 2.) The shower spray was rather poor/dysregulated. This does not appear to be a pressure issue...most probably a janky/clogged shower head = should be easily remediable.
All in all a great choice.
