Wow, the hotel is so far away from Pudong Airport, over 70km, so it will cost too much on the taxi fare, some 300RMB, I think. Cheaper ways is: take airport shuttle bus Line 6 to HuaShan Road. Get off the bus and take 沪青盈专线 (Huqingying Special bus Line), dropping off at Qing'an Road. Your hotel is there nearby.

Oh, yes, it is too late and there is no bus at that time. My suggestion is that you can take airport night bus to Hongqiao Airport. Then take a taxi the hotel, which may be a bit cheaper at taxi fare.
