When a guest asks how much the booking will cost, how do you know the total because when I look under my details I get a total however it does not include the entire additional fee Airbnb adds on.
First, @Ros52 , I tell the guests to go to the listing and put in the dates and number of guests, and the price will appear for them.
As a host, you can do the same. Preview your listing and go through the process as if you are going to book. The nightly rate and service fees will show up for you, giving you a total.
