One of the guests must be the booker, because it is not allowed to book a reservation for other people ("3th party booking" is only allowed if the booker owns a business account). So the review proces is not working. Better not take "3th party bookings" in future. Best regards, Emiel
Were you aware that 3rd party bookings are not supported by the Air BNB platform, @Hortensia1? As @Emiel1 has pointed out, the exception is under the business travel process in which a registered booking person such as an assistant can book. Under that process the traveler profile is available for reviewing the stay.
If you want to accept 3rd party booking you should use another platform and collect your own security deposit.
