A room near the La Plata Cancer Centre for a family from a village four hours away

My mother Dolores has been accepted for treatment at the La Plata Cancer Centre in La Plata, starting on Saturday in September. We live 166 km away in a village four hours away, 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 5 weeks. Two of us would stay: Dolores and me. We can contribute $40 a week and cook for the household if you'd like. Dolores 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.
