Nearly Perfect
I stayed over two weeks for business meetings and was impressed. 
Everyone has extremely helpful and super bend-over-backwards friendly. I mentioned to the booking agent that I'm a light sleeper - they remembered and gave me room away from the freeway and elevator. 
As always, Marriott beds are excellent. The decor is very nice - probably the nicest Marriott I've stayed in. My room was spic-and-span clean. Actually, everywhere I went in the hotel was spotless.
Room service was prompt and tasty. I have a special diet that they were happy to accomodate.
The hotel bar was surprisingly hopping during the week. It has an outdoor seating area with waterwall where you can have a cigarette. Seating was never an issue... It was nice to have a lively place to unwind after meetings. 
There are also many great places to eat in the area. Pack your roomy-clothes! My only complaint is that the breakfast buffet is a little pricey. Also, I was lucky enough to have a company-negotiated rate that included internet. Otherwise I probably would have booked in another hotel and missed out on a nearly perfect stay.
