Cancelling a booking
You can cancel a booking from your bookings page, at any point before the period has ended.
The host can cancel too. In both cases the dates are released at once and the space goes back on the market.
A booking cannot be moved to another time or another listing. Changing the dates is a cancellation and a new booking.
The reason recorded for a cancellation is shown to the other side. Write it briefly and clearly.
The full cancellation rules are in the cancellation policy on the site.
