Apartment is pretty much as advertised -- as with my other Uliv stay in CDMX, the responsiveness of the team was excellent. Anything you need (an extra towel, unlocking the laundry room, etc.) is immediately attended to once you message the team.
The building itself is not new, the walls are like paper, so sound travels, and the cleanliness of the apartment was underwhelming (floor was not properly cleaned when we checked in). The biggest problem we faced was with shower water temperature -- it fluctuated from scalding hot to ice cold every minute or two -- there are extensive instructions posted on how to operate the shower, but none of them seemed to work for us.
However, all this aside, the building has been renovated and is in generally good condition, and there is relatively fast wifi throughout (50-60 mbps). The views from the higher floors are wonderful. And the location in Polanco is excellent. Finally, the common rooms, especially the co-workngn space/business center are great.
