Who is familiar with Xi Xianyang Airport? Can you recommend a cheaper place to live?

There is a small hotel next to the east (left) underground parking lot of Terminal 2 of the airport. It's cheap there. You can stay there for one night.

If that's not good, Xianyang Airport Express Hotel in the east of 1 terminal (Xianyang Airport Express Hotel is only a few tens of meters away from 1 terminal) can also be used. Or go northeast along the interchange road in front of the airport terminal 1 to the airport east 1 ST road, where there is an airport guest house. Further northeast, all the way to Konggang East Road is a civil aviation guest house.
