We stayed 4 nights in a private double room. Definitely one of the nicest hostels you'll stay in. The bed was really comfy (especially for China hostels) and the on suite shower was really good.
We got a free transfer from the train station and the staff spoke good English so it was easy to arrange tours to things like the Terracotta warriors through them.
The cafe/bar is actually an independent called Cafe Blue rather than run by the hostel. As a result the prices for food and beer are more expensive than you would expect at a hostel. However, there was a supermarket literally across the street which sold beer for 2.5 yuan that you could drink at the table outside while socialising with others. There was also some great street food all within 100m of the hostel.
All in all a very sociable hostel with great rooms and a good location.
