A place to stay near Surakarta University Hospital while Kurniawan receives treatment

My father Kurniawan has been accepted for treatment at Surakarta University Hospital in Surakarta, starting on Sunday in February. We live 293 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 6 weeks. Two of us would stay: Kurniawan and me. We can contribute $20 a week and cook for the household if you'd like. Kurniawan will have some immune precautions, so a clean, smoke-free place would be ideal. A kitchen is a bonus. Thank you. Whatever you can give, even just sharing this page, means a lot.
