Hi @Jean9014
On your profile I see 4 different listings for what I think is exactly the same property?
If this is what you mean, yes, you should delete 3 of them. You want all of your bookings and reviews on one listing (and exact duplicates are not allowed by Airbnb).
For 3 of the listings, make very sure they have no bookings or reviews and then delete each in turn as follows:
Go to the Listings tab, click that specific listing, click the Settings icon, scroll down to Remove Listing.
Let us know if you have any issues!
