Anyone Familiar W/Hotels Near Mayo Clinic, Rochester, MN?

I have a lung condition that is as dangerous as cancer for me called Hypersensitivity Pneumonitis. Basically, I am having an allergic inflammatory response in my lungs that creates masses and destroys my  lung tissue (we can't identify what the culprit in my enviornment is). Mine seems to be particularly aggressive and came back only a few months after having a plum sized mass removed via thoracotomy.

My pulmonologist is at a loss on how to help me, so he referred me to the Mayo Clinic in Rochester, MN. Mayo sent me a booklet on local o hotels and said that most, if not all, near Mayo have shuttle services.

I need a clean room with absolutely no smoking near.

Has anyone used any hotel s near Mayo in Rochester that are reasonably priced (or better yet, offered a discount for patients?) and had an enjoyable stay? 

I was not sure where to post this, so I will try in several spots on the boards.

Thank you for your help!
