Beijing Airport to Hotel

Taxi is need, but it is not necessary to take taxi from the airport directly.
From the airport, you can take the shuttle bus line 3 to reach the Chaoyangmen Station and then take a taxi to reach your hotel.

Thanks Bella do you know cost of shuttle bus per person ? and cost of metro per person ?

The shuttle bus fare is CNY16 per person.

By MTR, it is a little complex. You can take Express Train to Dongzhimen fist and it costs CNY25 per person. Then transfer to local bus no. 106 at Dongzhimen and get off at Mishi Street Station, which is only around 280m from your hotel then. The bus fare is CNY1-2 per person.
