I just began hosting. Published my first listing sometime last night and at 1:40AM I received an inquiry about my listing. The individual asked "Can we check in at 3AM?". I don't mind however they have been on Airbnb apparently since 2019 and have no reviews. Airbnb says their contact info and identity have been verified but it seems strange I would get interest on my listing so quickly, so late at night, and from someone with 3 years on Airbnb but no reviews. The only information Airbnb gives me about their profile is a first name.
Something to add, I did say check in is okay from 4PM to 2AM because I am planning on just using a lock with a pin and giving the guest the pin once the booking is confirmed so they can have a seamless check-in experience and really come at any point in time because I know sometimes guests are traveling late.
