@Per-and-Åsa0
I looked at your listing and there seems nothing to be wrong with it.
It is in the search system, it has available days to book and even special promotions activated:
Sometimes it helps if you promote your listing on social media, external websites, etc.
Upload a nice coverphoto on your homepage and use the link to homepage:
https://www.airbnb.com/users/61362192/listings
(or change ".com" to the local Airbnb website you use)
BTW
Booking.com is a Dutch company !
They are heavily subsidized now by Dutch Governement due to Corona crisis:
