Not bad, but not blow-your-mind awesome...
Came here for a friend's birthday. Stayed on a Friday night in January and the rates weren't terrible. I believe we paid $115 a night.
As has been mentioned, the rooms were very modern in design. Note, not modernist. ;) Lots of black and silver, shiny surfaces... (for the cocaine?) Not really my taste, but I'm not holding that against them. It was very slick looking and consistent. Everything in the room seemed to be in good shape except for two of the outlets. They didn't work at all.
We chose one of the rooms with a view of the pool. By "view of the pool" they really meant - view of the pool if we hadn't planted about 20 trees in between.
Overall it's an ok place to stay if you are a rockstar or would like to be. For me, it was a little too far from the strip (a mile) if you are a walker. We took a lot of taxis so we wouldn't be drunk driving. Also, from walking through the front doors to the elevators to the room is easily a 20 minute walk. What the...!? While it was cool walking past the cute tattoo guys, it KIND of sucks after you've been drinking for 6 hours and just want to pass out.
Given the choice, I'll probably stay elsewhere in the future.
