PVG to Hilton hotel, Shanghai

You can take subway line 2 at the airport, and get off at Jing'an Temple Station, Exit 1. Then walk to the hotel directly.
Or you can take airport shuttle bus line 2 to City Termial Building (Jing'an Temple). After arriving, walk to the hotel directly.
If you want to take a taxi from the airport, the cab fare is around CNY 185.

Thank you. Taxi can be easily taken from airport?

Yes, it is pretty easy to take a taxi there. Don't worry!
