Family housing near the Makassar Cancer Centre: 3 weeks

My sister Novi has been accepted for treatment at the Makassar Cancer Centre in Makassar, starting on Sunday in August. We live 424 km away in a rural district, 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 3 weeks. Two of us would stay: Novi and me. We can contribute $10 a week and cook for the household if you'd like. Novi will have some immune precautions, so a clean, smoke-free place would be ideal. A kitchen is a bonus. Thank you. I never thought I'd be the one asking, and I'm grateful for every bit of support.
