I've got syncing working both exporting to a google calendar, as well as importing from a google calendar.
For exporting, the google calendar does show some very basic information, including the reservation confirmation string, last 4 digits of the guest's phone number and a title that shows it's "Reserved." These details are all very helpufl.
For importing, the airbnb calendar blocks off the dates of the event pulled from the google calendar. Unfortunately, that's it. There are no notes or details from what was created in the google calendar. This means I have to go look at the google calendar entry to see why the dates are blocked off. If a date is blocked off in airbnb, there's nothing to even indicate that it's due to an imported event rather than a manually block entered in Airbnb's app or website. Are there any options hidden away somewhere to allow Airbnb's Calendar to import any details from the Google Calendar event?
