I will be forever grateful to the young man at the front desk who was able to secure us two soft sleeper train tickets to Chengdu after the guy at the Beijing train station said there were none available. The staff in general were very helpful, friendly, and spoke good English. The location of the hotel is also a plus - 5 minute walk to the City Wall, 10 minute walk to the Bell Tower, 10 minute walk to shops and restaurants, 15 minute walk to the Mosque and street markets. We also did the Terra Cotta Warrior tour through the hostel which we enjoyed.
I would stay there again if ever in Xi'an, but am taking one star off for spotty WiFi and hot water.
