This depends on the time between placing the booking and the day of arrival. The deposit is 50% of the invoice amount. You must pay this amount immediately after receiving your rental agreement/invoice. The remaining invoice amount must be paid no later than 6 weeks before your arrival date.
If you book your holiday accommodation less than 8 weeks before your arrival date, you must pay the full invoice amount immediately. For some holiday homes, you pay the additional costs in cash upon arrival. On your rental agreement/invoice you will find a clear specification of all payment terms.
