We advise you to enter your unavailability periods in your calendar so as not to receive booking requests that you will not be able to answer positively and that would impact your referencing rating.
To do this, go to your account in the "Calendar" tab. Select the listing on which you want to enter your unavailability dates, then click on Calendar. You can then enter an unavailability period and indicate the reason. Don't forget to click on the "Add" button so that it saves and your availability is updated.
Note that an unavailability is automatically added when you have an upcoming reservation.
