Airbnb have the "progress" tab for you to see. Need to make sure operator share the ID/Pass with you.

Using operator is a bit tricky to monitor since they like to have a few airbnb advert for the same property.
Need to find a trustworthy operator (don't ask me, I don't use one).
But using operator also have lots of advantage i.e less headache.

Best way to gauge occupancy would probably see the electric bill. just download TNB app. if operator says one one booking one day but bill is 300, then it is time to find another. One more method would probably get some method to monitor internet usage.
