What is the best (cheapest) way to go to chi chen boutique hotel from Pudong airport?

Well, taking shuttle bus is not your prior choice. Upon landing, you are suggested to take subway line 2 at PVG, get off at Century Avenue Station first. Then transfer to subway line 9 to get to Xiaonanmen Station, Exit 2. After arriving, walk west around 200 yards (190 meters) to find the hotel. The whole way takes around an hour. It costs CNY 6 per person.
