I think maybe it is a courtyard, or ur setting leading to a courtyard when other tenants can see. I have lived in Stockholm Vasastan/Olstermalm/Lilla Essinge for 9 years so I know-how apartment/neighbours work in Stockholm.
Maybe try to host when u are away or during winter. In summer people spend time out even if it is out of reach in ur listing, they will still do it because they won't understand why u will refuse to let them use outdoor space. And if they come from a country when guys like taking the shirt off, nothing will stop them.
For the kitchen use, maybe rewrite house rules/ or stop kitchen use access in ur listing during the summer season and remind guests with same info when sending check-in instruction.
Or u can also limit to Light Cooking only allowed.
Good luck
