If your stay is under 30 days, the entire sum is paid upfront. If your stay is over 30 days, you will have the option to pay in 30 night instalments and only the first instalment is due upfront.
If your stay is more than 30 days and your check-in date is more than 7 days away, you have the option to only pay 10% of the first payment, then settle the 90% after 72 hours.
Your schedule of instalments payments are available for review on the booking page before you book. After you book your upcoming payments are displayed on your dashboard under Accommodation > My Accommodation Payments.
