At 1 hour before the check-in time indicated on your igloohome listing, a PIN code is sent via email to the guest's Airbnb email address (with the Airbnb host in CC). The PIN code needs to be activated within 24 hours of the check-in time and date.
If you would like to send the check-in email earlier, follow these steps.
Note: Check-in time is determined by the Airbnb listing when it is first connected. The check-in time can be changed on the igloohome app itself (instructions here), but will only apply to reservations confirmed after the change.
