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

My sister Anita has been accepted for treatment at the Hubballi Cancer Centre in Hubballi, starting on Sunday in April. We live 551 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 3 weeks. Two of us would stay: Anita and me. We can contribute $20 a week and cook for the household if you'd like. Anita will have some immune precautions, so a clean, smoke-free place would be ideal. A kitchen is a bonus. Thank you. Glad we found this place.
