The Kempinski is a newish business/convention hotel with fantastic service, but a little remote from the old city for tourist guests. If all you are doing in Xi'an is visiting the Terra Cotta Warrors, this is a great hotel because the remoteness of the location is not a detraction. If you plan to take in the old city and temples and great Muslim Market streets, this hotel is a good hour taxi ride away, sometimes longer in traffic. The concierge desk was very helpful, ask for Lincoln if you want the best English translation. The staff here goes out of their way to be helpful.
