A room near San Diego Transplant Centre for a family from a town in the north

My daughter Swati has been accepted for treatment at San Diego Transplant Centre in San Diego, starting on Tuesday in July. We live 204 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 6 weeks. Two of us would stay: Swati and me. We can contribute $145 a week and cook for the household if you'd like. Swati will have some immune precautions, so a clean, smoke-free place would be ideal. A kitchen is a bonus. Thank you. Please ask me anything in the questions section. I'll answer honestly and quickly.
