We like to stay in Muslim area of Beijing with good Metro or Bus stop.

Well, Niujie Street is a typical Muslim area in the city. It is adjacent to Guang'anmennei Station of Metro Line 7. The buses line 10, 48, 88, and 717 stop at Niujie Station. So it is very convenient for you.

For accommodation, you can consider these hotels: Home Inn at No. 1, Xili Road, Niujie Street; Hanting Hotel at No. 16, Niujie Street; GreenTree Inn Caishikou at No. 11, Shizidian Hutong. :)
