The apartment is just as described! With a door man round the clock and a touch pad for the individual apartment you never need to carry keys! The bedding and the towels are nice quality, there is soap and other necessities (plus a welcome basket) but I would suggest adding additional hooks for towels to dry from (by the sink and in the bathroom).
Having been to CDMX once before (staying at a different AirB&B across the park) I was surprised that the building seems to be only rentals with no locals living there. Note, that sound carries in this building and there is a fair amount of noise from out side too (music starting before 8am).
