My company has an arrangement with this hotel, and I have stayed several times over the past ten years. I have always found the hotel's personnel to be friendly and helpful, and this stay was no exception.
The hotel characteristic that I most appreciated was the very large room (suite) - much larger than the Hilton I stayed at in San Francisco the following week (which was much more expensive). I'm not sure if all the suites at this hotel are equally large; however, if not, ask for a room on the 5th floor.
As stated by others, the hotel is quite close to Sky Harbor Airport, but I did not hear planes at all during the stay. The hotel has a nice restaurant - I had only breakfast and a few evening takeaways - and the food was quite good. Internet access was $10 per day, but it was free to me because my company had paid a business rate.
There is also a running path along the Salt River Canal about half a mile East of the hotel. Convenient if you don't want to be cooped up on a treadmill or don't want to run along the streets.
Phoenix has a surfeit of gorgeous hotels, and this Doubletree can't be counted among them. Nonetheless, it fits the bill in several ways for people who have things to do during the day and want a comfortable, friendly, and spacious place to use as home base.
