Some of Booking.com‘s properties require a prepayment, also known as a deposit before a customers stay. This prepayment can be up to the total cost of the booking, or just part of it. The rest is then paid when customers stay at the property. However, for some properties, there is no deposit required, and customers will pay the amount in full when they stay at the property. It’s best to check the payment policies in the confirmation for more details.
