Hosting wanted: Đức travelling with Diệp to Hồ Chí Minh City for treatment

My mother Diệp has been accepted for treatment at the Hồ Chí Minh City Cancer Centre in Hồ Chí Minh City, starting on Wednesday in September. We live 487 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 4 weeks. Two of us would stay: Diệp and me. We can contribute $20 a week and cook for the household if you'd like. Diệp will have some immune precautions, so a clean, smoke-free place would be ideal. A kitchen is a bonus. Thank you. You're what makes this possible, and I'll never forget it.
