from Harbin to the airport? There is a bigger motel which has a large bus that goes every hour?

Oh, do you wanna find a hotel in downtown area that has airport shuttle bus?
If yes, you can stay at Tianyang Hotel. The price is CNY 200 to 300 per night. This one provides clean environment and big rooms. And you can take the airport shuttle bus at the main gate of the hotel. The schedules are from 07:00 to 17:00 with the interval of about half an hour. So the transportation is quite convenient.
The address of the hotel is No.186, Hongqi Avenue, Nangang District.
