Family housing near London Transplant Centre: 4 weeks

My mother Everly has been accepted for treatment at London Transplant Centre in London, starting on Monday in October. We live 286 km away in a town in the north, and hotel costs would use up what we have set aside for the treatment itself. We're looking for a room, granny flat or short-term rental within about 30 minutes of the hospital, for 4 weeks. Two of us would stay: Everly and me. We can contribute $60 a week and cook for the household if you'd like. Everly will have some immune precautions, so a clean, smoke-free place would be ideal. A kitchen is a bonus. Thank you. Even a small gift gets used right away and I'll thank you myself.
