Is there good transportation from Shanghai Sunisland internatinnal to the city center?

I heard there is a public bus line Shang-Tai Special Line from the Sunisland to the SH Gymnasium Station. Then you can use local subway line 1 and line 4 to anywhere you want to go in city proper area.
For the bus detail information, it is suggested to confirm with the hotel staff.

If this bus does not exist, you can take a taxi from the island to Songjiang University Town Station and use the local subway line 9 to reach city downtown area.
