I am new  with Booking. I synchronized with airbnb but it did not worked right away and i got a double booking.  The reservation is for 12.8 I called the guest on 29.7 telling him that there was a mistake but he insists to come.  what i am supposed to do?


Even when it is fully working sync is not in real time so always a risk of double booking.  Instruction above of how to contact booking.com
