@deedee22. You may already know this but when you have cancer treatment you are eligible to apply to stay at Hope Lodge at Mayo Clinic. When you scheduled for radiation therapy were you given an application? If so, you just submit it back to the desk and they will apply for you. Hope Lodge is at no cost.

The Radiation Oncology Dept has a concierge right in the department who can help you with available places to stay.

When I had radiation therapy at Mayo Clinic in Rochester I stayed with a wonderful network of homes and apartments called Serenity House Network.

The apartments and homes are completely furnished, very clean, and you have a full kitchen and laundry within the home. All the places are very reasonable in cost compared to staying in a hotel. I don't think any of the places are within easy walking distance of Mayo Clinic.
