hi can you tell me the cheapest way to get from Xian Airport to Citadines Central 36 Zhubashi?

You can take shuttle bus East Street Line from the airport to Grand Metropark Hotel first. The service hours of this bus line are from 08:30 to 20:30. It takes around an hour on the way. And the ticket fare is CNY 25 per person. After arriving, take a taxi to your hotel directly. The cab fare is about CNY 11 in the day time.
