Which is a good 4 or 5 star hotel along mrt line 15 and near to Beijing Exhibition Hall?

Do you refer to BJ Exhibition Center at No. 135, Xizhimenwai Street? If yes, you may stay at Best Western Ol Stadium Hotel, a very nice four-star hotel. It is located at No. 1, Datun Road, Beishatan, Chaoyang District. The telephone number is 86-010-64874433, and the email address is reservationbwolympichotelbj.com. The hotel is adjacent to Beishatan Station, Metro Line 15.

To BJ Exhibition Center, take bus line 695 from Beishatan Bridge East Station to Zoo Hub Station. Upon arrival, walk east for about 400 yards to it. Or, you can taxi there for CNY 30 to 35. :)

sorry, i am referring to the New China International Exhibition Hall near the Capital Airport.

Oh, I see. You may stay at Crowne Plaza International Airport Hotel. It is located at No. 60, Fuqian 1st Street, Tianzhu Area, Shunyi District. The hotel provides comfortable environment and nice service. The reservation hotline is 86-010-58108888.

It is about 800 yards to the southeast of China International Exhibition Center Metro Station, Metro Line 15. In addition, you can walk west to the exhibition center within 15 minutes. :)
