What is the best way to get from Kunming International Airport to Hualuxe hotel by public transport

Hi. What is the best way to get from Changshui International Airport to Hualuxe hotel by public transport by night? (flight landing after h.9 PM, or even after h. 1.30 AM).
If any public transport available, it will be easy to find a taxi or private transfer, and how much will costs?
Thanks
