what shuttle bus do i take to go to Beijing Sofu hotel 85 Huguosi street Xicheng district?

There is no direct shuttle bus that can take you to the destination.
From the airport, it is advised to take airport express to Dongzhimen first. Then take metro line 2 to Xizhimen Station and transfer to metro line 4 to Ping'anli Station, Exit B. Afterwards, walk east along Huguosi Street around 450 meters to find the hotel.
