Which Bus to Take?

Good morning!! I have a quick question and would greatly appreciate it if you could please answer it - I will be staying at the Hotel Novotel Beijing Peace from February 24, 2013 to March 1, 2013. The address is
3 Jinyu Hutong
Wangfujing

CHINA

I will be arriving from Detroit, Michigan (USA) through Delta Airlines. Which bus line do I have to take in order to get to my hotel? Thank you for your help.
