What do you mean by converting your listing?
If you mean that you want to be part of the « Category » Unique stay ?
You do not have to do anything … only wish that the AirBNB algorithm will one day see your house as a Unique Stay.
this is exactly what ABB says about categories
´Homes in each category go through a curation process. Millions of active listings on Airbnb are evaluated using machine learning to analyse titles, descriptions, photo captions and guest reviews. So it’s important to make sure your listing info is up to date and complete.´
