What is the best way to get at the grand soluxe hotel in Xi'an?

Since you don’t mention your departure place:
From the airport: Take Shuttle bus-Longhai Hotel line and get off at Longhai Hotel, then walk south along the road for 3 minutes, you will see your hotel.
From North Station: It’s not a long distance, so you can take a taxi directly to the hotel, which may take CNY30-40 and 20 minutes.
