How do I travel by Airport Express to the Doubletree by Hilton, Beijing? Thank you.

Hi, Donald. Upon arrival, you may follow guiding signs to take the train, and get off Dongzhimen Station. Next, transfer to subway line 2, and get off at Xuanwumen Station. Then, transfer to subway line 4, and get off at Caishikou Station. Afterwards, transfer to subway line 7, get off at Daguanying Station, and leave from Exit C. Walk for about 437 yards (400 meters), and you will find the hotel.
