Family housing near Marseille Children's Hospital: 6 weeks

My wife Martine has been accepted for treatment at Marseille Children's Hospital in Marseille, starting on Thursday in October. We live 399 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 6 weeks. Two of us would stay: Martine and me. We can contribute $50 a week and cook for the household if you'd like. Martine will have some immune precautions, so a clean, smoke-free place would be ideal. A kitchen is a bonus. Thank you. If you can't give, please share this page. It does reach people.
