Hello. I will be staying at Radisson Blu Hotel, 88 Nanjing Road, Shanghai.

No direct bus can take u there. I suggest you take airport shutttle bus line 6 to get off at Laoximen. Then transfer to a taxi to your hotel directly.

Or take Maglev from the airport to Longyang Road and then transfer to local subway line 2 to get off at People's Square. Get out from exit 7 and you can see your hotel.
