Hi, I would appreciate if someone that has self check-in to their properties could explain how it works. I saw that I need to enter my code in advance on my listing's page, but when and how do the guests receive the code? Is it a certain amount of hours before they arrive/ by their location or can I decide when to tell them? Will I be alerted once they received the message so that I can know that they're all set?
Thanks in advance!
