I'd like to confirm a booking. However it says there's an error on the hosts calendar therefore I can't book. How do I message or contact the host if the hosts details are not made available without a booking?
If you go to the listing and scroll down to the "Meet your host" section (it's below the map), there is usually a black clickable "message host" button.
Another way to resolve this would be to change the drop-down menu at the top of this page from Community Center to Help Center. You can then ask customer support to help you finalise the booking - they can communicate with the host to clear any issues.
