Unlike those star hotels in Shanghai, their price is about 168 RMB – 298 RMB (20 USD – 36 USD) per night for the standard room. I took picture of one of the Motel168 room in this entry: Cheap and Clean Motel in Shanghai – Motel168. The other two hostels are similiar. I cannot tell too much difference between these brands right now, since they are so similiar in price, room, and background.
To reserve, call their hotline or reserve online:
Jin Jiang Inn
Jin Jiang Inn and Rujia Inn are China wide chain hotels. You can find it in many cities around China. Motel168 just started and is only available in Shanghai.
