@Jose4483 When you go to your listing page in your hosting account and click on "preview listing", in the browser bar at the top of the page, the URL for your listing is showing there. You can send that URL to your friend and he can search it like that.
It appears that you have 2 listings for the exactly the same place. You need to delete one of them or you will get double booked if someone clicks on one and books it and then someone else clicks on the other and books it for the same dates. But make sure you don't delete the one that you already have reservations for. If you have reservations on both, you need to contact Airbnb to get that sorted out. ASAP.
