Hope it is not too later to tell you that info. You can take airport Bus line 5 to Shanghai Railway Station and then change to a taxi to the hotel. If you travel by subway or city bus, you should make several transfers. I recommend this one. You can go to Shanghai Railway Station by Maglev train to Longyang then by Subway Line 2 to People's Square and then Line 1 to Shanghai Railway Station, which may be faster than take airport bus.
