This is such a unique hotel that it's difficult to describe. Built right into the Buttes, it's more a combination of connected facilities. Numerous pools and hot tubs at multiple levels, a good fitness facility and restaurant (the Market Cafe; we didn't visit Top of the Rock), and great staff. There are a few reviews that mention how the rooms show some age, and it is true. But don't let that dissuade you--the rooms are still very nice.
I'd give 5 stars if they had a concierge lounge; I guess I've just gotten spoiled spending so much time at Marriotts for work.
One word of warning for people Uber reliant like me--the sprawling property is really confusing for drivers. While they can pick you up at any part of the hotel, meeting a driver at the main entrance (which is a 5 minute walk from some rooms) is easiest.
