@Buu0 In addition to what others have said, @Mario-and-Cata0, @Scott80, please know that since hosts are in total control of their pricing, it is a violation of Airbnb's Terms of Service to ask a guest to pay more than what they paid on a confirmed reservation. Here's the relevent text from the Terms of Service:
"Other Members will be able to book your Accommodation via the Site, Application and Services based upon the information provided in your Listing, your Guest requirements, and Guests' search parameters and preferences. You understand and agree that once a Guest requests a booking of your Accommodation, you may not request the Guest to pay a higher price than in the booking request."
So be very careful!!
