I'll arrive in Xian Friday at 23:00. My Hotel is Eastern House Boutique Hotel. Which bus do I take?

You can ticket the airport shuttle bus Xishaomen Line to Airport Business Hotel first. This bus will operate till the last flight arrival. The ticket fare is CNY25/person. Upon arrival, you are about 4 kilometers to your hotel, so you may catch a taxi to the destination directly.

Thanks so much!
