1. Jishuitan take the subway line 2 at Xizhimen and change the subway line 13 at Dazhongsi, get out of the subway and take the bus 425 (Yuntong 101) across the road and get off the bus at Changchunqiao Road;
2. Jishuitan take the subway line 2 at Xizhimen and change the subway line 13 at Zhichun Road and change the subway line 10 at Baigou Village and change the bus 394 to Changchunqiao Road. Get off at Changchunqiao Road.
Recommended to take the first route, less change once the subway, 425, Yuntong 101 buses are also a lot, from Dazhongsi to Changchunqiao Road also need to sit only 4 stops. (Don't go to Bagou, that is far away instead, from there to take 394 and back again have to walk across the road again to find.)
Then get off at Changchunqiao Rd. and turn right at the intersection in front of you (you can see it when you get off at 425 Rd.), and then turn right at the 40th North Hotel, which is about 50-60 meters away.
Don't listen to what Wanliu Middle Road South Exit, Suzhou Bridge West, 200 meters 300 meters fooled; North Forty Degree Hotel nearest station is one (Changchunqiao Road).
