Always review the cancellation policy before booking — it's displayed on the listing detail page, again on the booking page before you confirm, and included in your booking confirmation email.
Each host sets their own cancellation policy. Refunds are enforced by the host in accordance with that policy. Crewdogs facilitates this process as the Merchant of Record; we do not dictate refunds like other OTAs. For a full overview of cancellation policies, see
