As soon as we receive your reservation, KOSMOS SANTORINI will accept it or not depending on the availability.  Normally accepted via our online booking system. This is the reason why making your reservation some time in advance is important, especially during the peak season of July-August. In order a reservation to take effect, a down-payment is required. These payments will be RESERVED in your account until the final confirmation of the booking.

In case a booking is not confirmed for any reason, KOSMOS SANTORINI Company does NOT have the obligation to reserve a car if the advance payment is not completed.

In case the booking is confirmed, the down-payment will be deducted from your account by KOSMOS SANTORINI respectively, so make sure that the amount for the down-payment is available in your account.

In case KOSMOS SANTORINI cannot confirm your order for any reason a cancellation e-mail will be sent to you with suggestions on changing your order; no payments will be captured from your account.

It is essential that you provide a correct e-mail address and mobile phone number, as the voucher contains important information on the delivery of the rental car at your destination.

Delivery instructions and telephone numbers will be written on your voucher. No refund is made due to unreceived or unread voucher.




In case the booking is confirmed, the down-payment will be deducted from your account by KOSMOS SANTORINI respectively.

The balance has to be paid upon delivery of the car either by Credit Card in the name of the driver or in cash. A major Credit Card is required for guarantee reasons.

Our online booking system accepts payments in advance via PayPal (account or Credit Card Visa & MasterCard), Credit Card (off-line process) and Bank wire transfer. In this case you should send us by email your Bank’s receipt for direct confirmation of the rental reservation.
