1. Now the system will accept booking requests for me if they met those requirements. But how can I change it to everytime they book, I need to accept them by myself?
2. What if the guest gave incorrect information (they said they were 2, but turned out to be 4 people living in my property), what can I do?
@Chen1 do you have IBooking turned on? You can't accept them yourself with that turned on. You will need to turn that off.
You need to call ABNB and tell them about the extra guests first. Then you need to contact the guests and tell them what you charge for the 2 extra people and they need to pay you that amount. You can request money from them or they can offer money to you.
