Hotels near Chengdu are cheaper, safer and cleaner.

Handu Hotel next to the exit of North Station is cheap.

128-288 will do.

If you don't like it, take a taxi to Southwest Jiaotong University, which is the nearest university to the North Railway Station. There is a comfortable hotel chain next to it, probably 158 yuan.

If you take a taxi 10 minutes, you can get to the city center. So live anywhere. Hotels in Chengdu are not expensive unless they are hotels.
