Airbnb have an Open Homes program for Medical Stays, which you might find useful?
Generous hosts from the community provide free housing and Airbnb collects donations from the public through its Open Homes Fund, to contribute to non-profit organisations such as the Hospitality Homes, Fisher House Foundation and Make A Wish Foundation, that help patients, families and caregivers in need of support and assistance when their loved ones are receiving medical treatment or critical care.
There may be some limitations as to who does or doesn't qualify for assistance, but it's worth reaching out and inquiring anyway.
In the case of Medical Stays, guests can search for and book an Open Homes listing directly for themselves, or a nonprofit staff member may make the booking on their behalf.
