Nice room, generally as advertised. Michael was extremely responsive and friendly.
Note that the room is not really on the 51st floor, as there are no floors in the 40s. View was still excellent.
We weren't expecting this unit to essentially be a hotel room. When we checked in, they took a credit card and charged us $100, even though we prepaid through Airbnb. They said it was a deposit that would be refunded. It hasn't been yet, although we just checked out today. Normal hotels will authorize charges on a credit card but only charge if something is purchased. We were actually charged. I suspect we will be refunded, but it feels shady.
