Hi,
I’m new to AirBnB but know that area of Sweden so thought I’d make a comment!
I think your listing looks fine - I would book it!
It is only available for such a short time in the Summer that I think it might just take a while for people to book perhaps.
The cat may put some people off but equally there are lots of young people living in apartments who cannot have pets & live the idea of being a pet ‘owner’ for a few days.
Good luck!
