If your reservation has been made through an intermediary booking channel such as Airbnb or Booking.com, you will have to check the payment and cancellation conditions included in the platform itself.
If your reservation has been made through Avaibook:
Cancellation policy: a full refund of the advance payment (30% of the total price of the reservation) will be made for cancellations made up to 30 days before arrival. After that period, the amount corresponding to the advance payment will be lost.
Payment policy: 30% of the price of the stay will be charged at the time of booking as an "advance payment" to the credit card provided by the holder of the reservation. The remaining 70% will be charged at the time of arrival. €150 will also be blocked in cash or credit card as a "deposit" at the time of arrival. If there is no reason why the deposit must be withdrawn, this amount will be released or returned within 48 hours after departure.
