My arrival to Beijing Capital Airport will be at 2am.

You can stay at Yamei International Hotel at No. 42, Gangshan Road. It costs about CNY 250 per night. You can dial at 86-010-64578383 to book a room. The hotel provides clean environment and warm service. It is a 5-minute drive from T3; 8-minute drive from T1 or T2. Have a try! :)

Hi, appreciate your suggestion. What about hotels that are within walking distance from T3? I am worried that at 2-3am, getting taxi is a challenge. Thank you!

Actually, taxis are avaiable around the clock. You needn't worry about this. The hotels within walking distance from T3 are either very expensive, or exclusive to Chinese. But you can consider Airport Tianyuan Hotel at No. 9, Tongshun Road, Liqiao Town. The hotel provides free pick-up service. It costs CNY 120-250 per night. You may dial at 86-010-57745533 to book a room.
