I just stayed at the HIE Bell Tower. It's a few steps from the airport bus terminus (Bell Tower Hotel), very close to the subway stop (Bell Tower), and within a 10 minutes' walk to the Muslim Quarter, decent shopping, and one of the more remarkable nouveau Shaanxi-cuisine restaurants at Shuyuanmen. The Ramada is located a little farther away, north of the Bell Tower. But HIE is still HIE. The rooms are small and the service is plain -- the norm.
