Family housing near Lahore University Hospital: 3 weeks

My sister Farah has been accepted for treatment at Lahore University Hospital in Lahore, starting on Sunday in October. We live 309 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: Farah and me. We can contribute $20 a week and cook for the household if you'd like. Farah 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.
