For Instant Book hosts only
Hosts who use Instant Book may be able to cancel penalty-free if they have concerns about the reservation or a guest’s behavior. Calendar inaccuracy, confusion about pricing or availability, and extenuating circumstances are not covered by this policy.
If you're an Instant Book host and have concerns about a reservation or a guest's behavior:
- Go to Your Reservations and find the reservation you need to cancel
- Click Change or Cancel
- Select “I’m uncomfortable with the guest’s behavior”
- Provide a reason for the cancellation
Once you complete these steps, the host cancellation penalties for this reservation will be waived, and we’ll help your guest find another place to stay for their trip.
If it's within 24 hours of check-in, contact us instead.
