We recently spent 2 nights here whilst visiting Terra Cotta Warriors. I could only describe it as mediocre! First night the air conditioning did not work and fan rattled so loudly we hardly got any sleep. The access card was very temperamental. The carpet had not been vacuumed properly and was very 'crunchy'! To use the pool you MUST wear a swimming cap and walk through a disinfectant trough before entering the pool area.
But the worst thing is location. It was very difficult to get cabs in and out of town (5 -11k depending on where you are going). Our shortest wait was half hour and longest to come home in excess of one hour. Town was very interesting but transport made it a stressful activity.
