The cancellation notice from Nicolas for the second day of a two day booking was dated and e-mailed to me on the early afternoon of his second day, from his car.Cancellation policy per Air Bnb (booking confirmation paperwork) requires 24 hours cancellation notice to receive a prepaid refund for reasons other than extreme emergency. This allows time for host to perhaps book someone else and not suffer the loss of confirmed booking income. Conversely, booking confirmation saves guest from the inconvenience and expense of last minute cancellation by host except under extreme emergency.
Fees received by Air Bnb under most cancellation circumstances are also non refundable. These have remained fair rules for both host and guests during the
entire time in which I have been associated with Air Bnb--nearly 200 guests . I think a more timely communication( by phone or in person)when Nicolas first learned of his friend arriving down the coast one day early would have served us both better.
