Let me start by saying that I am EXTREMELY picky about beds. I have horrible arthritis in my legs and back and require a bed which is firm but also soft. I sleep on a pillow top mattress at home and if the hotel I stay in does not have a mattress that is comfortable to me I don't have a very nice time. This hotel was a great experience for me.
I stayed at the Hampton Inn East in Flagstaff for 4 nights at the end of May 2011. Our party had two rooms, one room with a couple in their 80's and our room both of us over 50. We had never been to Arizona before so this was our first trip. We found the Hampton to be delightful. Beds were super comfortable, the room was extremely clean, fresh towels everyday, linens fluffed and beds made everyday. Service at the front desk was super and they were always willing to help and were friendly. Some had commented about "train noise" and there is a sign at the front desk about it but we didn't find it disturbing. I think unless you are an EXTREMELY LIGHT sleeper this is a non issue. The continental breakfast was good and sufficient for our needs. One of our party fell on the last day (not at the hotel) and required crutches. The hotel doesn't have a wheelchair but they did allow us to use one of their office chairs to get the guest to the room. As I said, they were extremely helpful. This is a great location for exploring and a good base of operations, if you will. We went to the Grand Canyon, Snowbowl, Painted Desert, Verde Canyon Railroad, Senoda and downtown Flagstaff and found this to be an excellent location to base our trip from. I would highly recommend this hotel and would stay here again should I ever go back West.
