From xianyang Airport Terminal 3 to Grand Noble Hotel, is there any shuttle bus?

You can take airport shuttle bus line and get off at Bell Tower Hotel first. Then walk east around 1km to find the destination.

Or, upon landing, take subway Airport Line and get off at North Railway Station. Then transfer to metro line 4 to Dachaishi Station, Exit C. Afterwards, walk west around 850 meters to find the hotel.
