what bus from Dongzhimen subway station to IKEA in Beijing? or is there subway?

oh, i see. There are several IKEA stores in Beijing.
If you don't have a designated one, you are suggested to go to the IKEA in Daxing District.

Take subway line 2 to Xuanwumen Station. Then transfer to line 4, and get off at Xihongmen Station, Exit B1. After arriving, walk to your destination directly.

Hope helpful! :)

sorry, the one closest to Dongzhimen Station, near Siyuan Bridge, to the north of Dongzhimen. thanks
