@1hockeyjeff I have not been to the Phoenix Mayo campus, but on the Mayo website there is some information for Phoenix about accommodations for an extended stay for long term cancer or transplant treatment called the Village at Mayo Clinic. Here is the link to the page on the website which has a phone number to call.

"The Village at Mayo Clinic is an on-site hospitality house — a low-cost, extended-stay lodging option. These spacious casitas are reserved for families of out-of-town patients who are receiving transplant or long-term cancer treatment. Call 480-609-1324 for lodging and updated information."
