Arrive at Doubletree by Hilton Beijing from Capital Airport.

When you say take the express train under Dongzhimen, and then transfer to a taxi, it's ok at night. If there is a special traffic jam during the day or during the rush hour, the taxi fare is estimated to be more than 4 yuan. It is suggested to take the express train under Dongzhimen, get off at Xuanwumen on Line 2 subway, and then take a taxi, which is very close, estimated to be 1 yuan.

or you can take the airport bus, as upstairs said, but this route is very blocked.
