The best way is to take airport bus. The hotel is very close to Shanghai Railway Station. You can take airport BUs Line 5 to the railway station. Then take a taxi to the hotel with paying the minimum taxi fare I guess, less then 15RMB. If you take maglev train, it will be a bit complicated. From Longyang Road, take Subway Line 2 to People's Square. Then change to Subway Line 8 to Zhongxing Road (two stops only). Get out from Exit2 and walk 5 minutes to your hotel. Or you can take taxi from People's Square to hotel directly. It will be easier if you have heavy lugguage.
