Stayed here just for a night when I was in town to see NIN at the US Airways Center. The price was super cheap and HGI's are my favorite brand of Hilton so it was a no brainer.
Pros: shuttle to and from airport. A block away from public transit (the shuttle will take you/pick you up there if you ask.) Coupons for a free well drink if you're Diamond (I'm guessing Gold too but don't quote me). I didn't use it but it's a nice gesture.
Cons: not much around the hotel so you need to have a car or be content with transit to get food, etc.)
I'd definitely stay here again if I was in Phoenix for an event or if I was stuck in Phoenix due to a mishap at the airport.
