Guests are given a generated door lock code that will only work for the dates that are booked. Once the check-in time is available the code will then be activated to check-in.
The owner is notified by the door system that the guest has arrived. No need to contact the owner. The guest is able to arrive at any time of the day.
When the guests are ready to depart a simple code *0* on the door lock will notify the Owner that they have Checked Out. All codes expire at 11 am on departure day.
