What is the best way to get from Pudong Airport to the Sheraton Grand?

It's suggested to take metro line 2 from PVG, and get off at Century Avenue Station first. Then transfer to line 4 to get to Tangqiao Station, Exit 3. After arriving, walk southwest around 300 yards (270 meters) to find the destination. The whole way takes around an hour. And it costs CNY 6 per person.
