how do I find a cheap holiday inn in nanjing near the main train station?

Is a chain hotel ok for you? If yes, the Motel 168 nearby is recommended. The distance to the train station is about 0.6 miles. And the price is CNY 150 to 200 per night. It provides warm service and clean environment. This hotel is located at No. 140 Heyan Road, Jiangning District.

If you insist in staying in a holiday inn, no a suitable one is within walking distance. You may consider the Holiday Inn Aqua City, which is around 5.5mi away. Its exact location is
no. 1, Jiankang Road, Qinhuaiqu (near Fuzimiao).
