Hi, will you take Air Asia flight?There is one shuttle bus everyday operated by Air Asia for their passengers, between Shanghai Huangpu Bus Station (1588, Waimalu, next to Nanpu Bridge Station of Subway Line 4) and Hangzhou Airport. In the event of flight schedule change, this bus service will depart 1 hour after the arrival of AirAsia X flight.
If you won't take this airline or will not use the Air Asia shuttle bus service, it is more effective for you to get to Hangzhou Train Station first by taxi (about 100RMB for 40 minutes) and take bullet train to Shanghai (54RMB/65RMB for 1.5 hours). Then take taxi to 300, Wuning Road.
