Overall very disappointing -- the two amenities they promote as key to the offer 'the business centre' and the 'gym' are in the basement, which is not healthy -- the basement is filled with damp, and you can feel it heavy on your lungs.
The rooms are average, I was given a poor inward facing one with little natural light in the living room. There is significant traffic noise, but this was expected given the corner location -- the same as most of the other options in the area.
Wifi was fast, and the roof top was pretty good.
My real frustration was during checkout, when I had arranged via WhatsApp to check out at 12 (not 11)... I did originally ask for 12:30 but they couldn't grant me this, not even for a fee. I had an important call with a client, so wanted a quiet and private place -- but then at 11:15am I get a loud knock on the door, interrupting the call and clearly not honouring the late check out. It was a real breach of any reasonable service -- showing this place is not ran by professionals.
I was looking at ULIV for other long term, but will avoid at all costs from this experience. I would advise you find somewhere else, there are many better options in CDMX.
