Just fabulous
I am not sure I can add much to the reviews here. We stayed in a Valencia Casita, quiet private room at the back of the pool area in lovely gardens, with a private patio. Our room had a shower, 4 poster bed, fireplace with gas fire, seating area, desk, dressing area. The room was kept spotless with service twice a day. The resort is probably better for couples than families with children. The grounds are beautiful and there are plenty of places to sit and enjoy a drink or relax. The pool area though small is spacious enough and there were always sunbeds. The hot tub is very warm!. There is a small gym at the pool area. We ate at T Cooks one evening which felt like a special occasion, There are some very good restaurants in Phoenix, but the location makes this special, we sat outside at the back kept warm with a fire and patio heaters. The best thing about the resort is the customer service. The car valets, reception, pool staff are all first class. 
The spa was very good, comparable to anything I have had in other 5 star hotels, and the facilities were good. The bar was nice for a drink or snack, and had live music some evenings.
There were some private and corporate events on but nothing detracted from our stay.
Location to the south side of Camelback mountain and accessed off Camelback road was very convenient for golf, shopping (the hotel is mid way between the Biltmore Mall and the Fashion Mall) and easily accessed from the airport. Tip if you are shopping try the new Tanger Mall at Glendale by the football stadium. If you are there for golf and want somewhere relaxed and friendly try the Silverado Municipal course at Scottsdale, clubs can be hired.
Put it this way, I am sure we will be visiting Phoenix again and I cant see us staying anywhere other than the Royal Palms.
