Family housing near Pune Children's Hospital: 4 weeks

My father Hitesh has been accepted for treatment at Pune Children's Hospital in Pune, starting on Wednesday in February. We live 419 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: Hitesh and me. We can contribute $25 a week and cook for the household if you'd like. Hitesh will have some immune precautions, so a clean, smoke-free place would be ideal. A kitchen is a bonus. Thank you. Thanks for being kind about this.
