Put this in your house rules:
Quiet hours are from 9pm to 8am. There are working professionals in neighboring units who have to be at work at 8am. They will not hesitate to call the police if you are loud or throw a party.
When people ask for a discount:
I’m sorry, but I keep my prices low and have almost 100% occupancy, so I don’t offer any discounts.
When people ask about payment or deposits:
Airbnb handles the financial end, and they don’t give me any visibility into how it works. If you have questions about payments or deposits, you’ll need to call them.
