Airport Train or Shuttle from PEK to my hotel?

I would suggest you take shuttle bus line 2 to Yonghegong Lama Temple. Then you can transfer to local subway line 5 and get off at Dengshikou. Leave from exit A and you can walk to your hotel in around 1.2km. And there is around 3.5km from Yonghegong to your hotel, so you can also take a taxi to reach then.
