Hotels in Shanghai

Dear Sir,
I will be taking the shuttle bus operated by AirAsia for their passengers from Hangzhou Airport to Huangpu Bus Station (1588, Waimalu, next to Nanpu Bridge Station of Submay Line 4 ) on the 27.11.2012, reaching Hangzhou Airport at around 10.20pm. How long it takes to reach Huangpu Bus Station from Hangzhou Airport? Can you kindly suggest a few middle class hotels around Shanghai Huangpu Bus Station or Nanpu Bridge Station of Subway Line 4, hopefully within walking distance because will be arriving at Shanghai Huangpu Bus Station, probably way after mid-night by then. Please kindly advice. I thank you in advance.
