Hi @Nina143, if you are on the old dashboard (Airbnb is rolling out a new dashboard) go to Manage Listing > Calendar and More. At the bottom of the left side menu you will see a box where it should currently say "Listed" . Click on that and you will have the option to Snooze or Unlist.
While both Snoozing and Unlisting accomplish the same result (making your listing unavailable to the public in search) they work slightly differently. With Snoozing, you enter specific dates you want your listing unavailable. After the end date, Airbnb will automatically re-list your listing so you have to be prepared for that. Selecting Un-list will make your listing unavailable indefinitely until you select Listed again.
If you are on the new Dashboard, select Manage Listing in the drop down menu under Host. Under Listing Details, the very first item is the Listed section. Select Edit to Snooze or Un-list.

Be sure not to permanently deactivate your listing!
