3.5 stars.
It's a clean hotel. No smoke and it smells great. This hotel is usually the hotel of choice for my coworkers and I when we go to Vegas. Valet is pretty quick and the walk isn't too far to front desk and guest elevators.
The bath tub is a bit small for me (I'm 6'2)
There isn't any good options for coffee though and it gets kind of boring at night since there isn't a casino. I usually just walk to Aria for that.
Wouldn't be my most ideal choice for a hotel stay but when I get special rates I would definitely stay here.
