Because you pay the listing member directly, cancellation and refund terms are whatever you agreed with them. Vaytoven never took the money, so there is nothing here for us to refund and no cancellation policy of ours that applies to your stay.
Agree the cancellation terms in writing before you pay anything. What happens if you cancel, what happens if they cancel, and what is refundable are all worth settling up front.
If you cannot reach the listing member or you believe a listing misrepresented the property, raise a Trip Support request. We keep a record of the offer and the correspondence, and we will help you make contact — but we cannot issue a refund on their behalf.
