A room near Medellín Children's Hospital for a family from a village four hours away

My daughter Marta has been accepted for treatment at Medellín Children's Hospital in Medellín, starting on Thursday in September. We live 513 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: Marta and me. We can contribute $45 a week and cook for the household if you'd like. Marta 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.
