Usually when I'm on business in Tianjin, I stay at the Friendship Inn at #5 Xiukang Lu. It's a simple hotel with very simple furnishings that probably won't last for long, and the breakfast is almost inedible. However, for under 200 yuan with their VIP card, relatively newly built, plenty of good restaurants in the neighborhood, and rooms oriented to the back of the building that are very quiet and get sun all day, I can't imagine a better value. I sleep great, can work all day in the sun, and eat well. Some foreigners come, so Chinese is not necessary, but you will be staying in a real local business hotel.
