My sister and i stayed in Yuan's house for two nights, the room is really comfortable, with our own restroom. We also share a functional kitchen with yuan. The room is clean and the bathroom is equipped with everything you need. Yuan is really nice, helped us a lot and gave us full privacy. The location is also great, walking to the milan central station within 10 minutes and the the nearest station to the duomo takes only 10 minutes. I would highly recommend to stay in their airbnb in Milan!
