So sorry to hear about your son, my heart goes out to you. Hoping the trial works out successfully for him, and that there are brighter days ahead for both of you.
On Tuesday of this week, Airbnb announced a strategic partnership with the Cancer Support Community, through which the Airbnb community will provide free housing for cancer patients and caregivers, provided they meet certain criteria. Full details in the link below. Very best wishes to you both.
