A room near the Moscow Cancer Centre for a family from a rural district

My sister Milena has been accepted for treatment at the Moscow Cancer Centre in Moscow, starting on Sunday in November. We live 331 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 5 weeks. Two of us would stay: Milena and me. We can contribute $45 a week and cook for the household if you'd like. Milena 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.
