Yes, you can cancel or modify your booking, but please keep the following in mind:
In the event that the free reservation is cancelled (which must be done at least 24 hours in advance), and in the case of pre-paid rentals, Sirlet Inversiones S.L is not responsible for, and will therefore not reimburse, any sums affected by currency exchange rates, other commission costs or charges, or third-party fees.
In the event of cancellations made with less than 24 hours notice, Sirlet Inversiones will charge 100% of the cost of the reservation. You explicitly accept the amount to be charged to the debit or credit card provided, renouncing any complaints or legal action to be taken against Sirlet Inversiones regarding this matter. Pre-paid amounts will not be subject to refund.
