I arrive 14 sept 08.55 at the airport in Beijing. What is the best way to the Dragon King Hostel

First of all, I need to clarify that it is the capital airport and the hotel is located in No.78, Dongsijiutiao, Dongcheng District.
If so, you can take airport shuttle bus line 3 to Dongsishitiao, then walk about 1700 yards to get there. The bus departs from 07:00 to 24:00 every 30 minutes. Ticket fare is CNY21 and duration is about 80 minutes.
Or you can take airport express to Dongzhimen, then change to subway line 2 to Dongsishitiao, then walk to the hotel. Duration is about 70 minutes and ticket fare is about CNY28.
