We stayed at Shuyuan ‘Party’ Hostel, the original hostel in Xi’an.
Definitely a social place to stay with a very popular local and travellers bar in the basement, named ParkQin Bar. You also get a Free Beer Token, on check-in, which you may redeem at any time.
A bed in a dorm of 8 people at this hostel cost us 35RMB/ AU$7 p/p p/n. Breakfast was a little pricey at 35RMB/ AU$7 but you get to order from the western menu and it is freshly cooked for you. It includes a cup of coffee or tea. Not too bad if you are sick and tired of noodles or soup; which we are not!
