My arrival time in Shanghai airport is 1220am midnight. Is there any bus to Haodu hotel in downtown?

Do you refer to Shanghai Pretty House Haodu Hotel? And will you land at Shanghai Pudong Airport?
If yes, upon landing, you are suggested to take airport shuttle bus Night Line to East Yan'an Road Middle Zhejiang Road first. The service hours of this bus line will till 45 mins after the last flight arrival. Thus you can catch it. After that, just walk southeast around 250 meters to find the hotel.
