How to reach hotel through shuttle service (Beijing Airport Shuttle)

How to get to Beijing Dongsi Super 8 Hotel from Beijing airport?
Hello! I am arriving at Beijing (PEK) around 10:00 PM. Riding a taxi is quite expensive as I am on budget trip. What's the best but safe way to get to the Dongsi hotel?

Address: No.137 Dongsiwutiao, Dongcheng District, Beijing, China
Area: Dongcheng, Dongzhimen/Workers' Stadium
Overview: The hotel is located in the Dongsi business, culture and tourist area.

Thanks in advance.
