I would really like to give a single occupancy discount, is that possible? I’m happy with my pricing for 2 people, but think it maybe a little expensive for one. Also is it possible to put a minimum 2 night stay?
In your listing's Calendar go to the pricing tab (on the app you click the Settings icon on the Calendar to find the Pricing and Availability tabs). In pricing, scroll down to Additional Charges and then down to Extra Guest Fee.
For minimum stay, click the Availability tab next to the Pricing tab. It's the first option there.
