How about Jinghu Hotel in Jiulidi Campus of Southwest Jiaotong University?

I'm from Jiaotong University. Jinghu Hotel is good, with about four stars, good supporting facilities and beautiful environment. Especially in recent months, the school has renovated the surrounding green belts, which is very good. Single rooms are usually around 120 a night. You don't have to make a reservation, but if you are afraid of being booked, you'd better make a reservation. Business there is good, but you have to divide your time. If many leaders come out for meetings or business trips, there may not be many rooms. There are usually vacant rooms. You can ask directly, it's near Jinghu Lake.
