Kunming Airport accommodation

It is mentioned on this site, there is accommodation within the airport. Where can I find it?
I am going to arrive after midnight (1:30) and traveling to the South bus station in the morning. So, I will have only about 5-6 hours to sleep. Therefore, I would like to sleep at the airport if there is any accommodation there
(example: at Hong Kong airport rooms can be rented by the hour also ....)
