Exceeded my expectation
I picked a wrong day to visit the Valley of the Sun, it was May 22, and they issued excessive heat warning for the area. The temp reading was 108 degree at noon, so there went my plans for outdoor activity that day. I landed in PHX in the morning, although the check in time is 3pm, I called the hotel and let them know I have no where to go in this weather except for sitting in a restaurant or shopping mall. Ken was the person I talked to and he let me checked in at noon. Awesome!
The room was clean with your typical Radisson decor, although I am not a fan of sleep number bed, that did not bother me at all. The lobby, restaurant, hallways and rooms were nicely appointed as well. 
Overall this is 3-star Radisson property in my opinion, it was the service that made it a 4-star hotel!
