Hello! I have listed my listing for quite some time and my co host has also listed the same listing is it possible that guests only see only one listing?or they see both of these listings.
You shouldn't have a duplicate listing on Airbnb. You and your co-host should work on the same listing. Judging from the problems that people on this forum have reported when they intentionally or accidentally get flagged as a duplicate listing, it's not a good idea.
