I am staying in Vienna Hotel xian train station. ( the railway station,south branch)

Is your hotel located at no.53, Jiefang Road? If yes,you may take the airport shuttle bus Longhai Hotel Line to the last stop. Upon arrival, you can find your hotel in your sight. This bus will work to 02:00 at midnight, so you can take it when you arrive. The duration is around 70 minutes and the ticket fare is CNY25/person.
