The payment of a reservation is made directly on the site.
Thus, as soon as the reservation is paid, it is confirmed.
The traveller receives a code when he pays his reservation on the platform that he will have to communicate to you after the first night spent at your place. In the excitement, he might miss it. Remember to remind him!
You got the code? Great! Go to the reservation page of the traveller in question, there is a box on the right side in which you can insert it.
So, from the moment you insert the code, the transfer is in progress.
Remember to save your bank details (IBAN) on your profile so that the payment is transferred directly to your bank account.
