For a definitive confirmation of the reservation, it is required to send the credit card details as a deposit.  We will send you a simple form tasking the name of the holder, the card number, the type, the expiry date and the security number (you can find it on the back, last 3 numbers on the right). No amount will be charged to your card, it is only used as a guarantee. It is also possible to confirm with a deposit by bank transfer.
