Family housing near Fort Worth University Hospital: 5 weeks

My husband Ezra has been accepted for treatment at Fort Worth University Hospital in Fort Worth, starting on Friday in November. We live 240 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 5 weeks. Two of us would stay: Ezra and me. We can contribute $180 a week and cook for the household if you'd like. Ezra will have some immune precautions, so a clean, smoke-free place would be ideal. A kitchen is a bonus. Thank you. Thank you so much.
