Jacky‘s place is really modern, clean and well organized. I shared the apartment with two other guests and two residents. (I think Jacky and one girl that does not speak English).
It is usually really quiet. Jacky has a great eye for detail and the rooms are equipped with many things a traveller might need (toothbrush, air plugs, outlet converters, etc.). The whole house is automated via Xiaomi smart home solutions. The shared rooms (except for the bathroom, of course) are also monitored by cameras. You have to know for yourself if thats a plus or a minus to you. Also, there are many little signs everywhere that tell you how to do stuff.
All in all I can recommend this apartment if you looking for quiet, very well equipped place to stay.
Try to use the chinese adress or you will have a difficult time finding the right place!
