@Daniel9339 The House Rules that currently appear on your listing are just the tickbox ones: No Smoking, No Parties, No Pets. This doesn't sound like a rule-breaking situation, unless the guests are subtly throwing cigar parties with their hidden Labrador.
It's very normal with home-sharing that sometimes you get guests that you just don't click with - even after carefully vetting them in the correspondence. And considering how intimate the space is in a Berlin apartment (I know something about this, of course), it is viscerally stressful when people you don't like are occupying that space. That's why it's very important to set a maximum stay which reflects the longest amount of time you're willing to live with annoying people.
But tolerating these guests' quirks is literally your job. It's great when people greet you like friends every day even though they're paying to stay with you, but the guests don't actually owe you social comfort because, to quote Don Draper, that's what the money's for.
If there are just a few days left in this stay, you're best off not poisoning it with gestures that only make the annoying guests feel unwelcome. But if it's a long term stay, and these people are basically flatmates, you might have to drop the subtlety and tell them that this living situation just isn't working out; in that case, you give them a reasonable notice period to find somewhere else to say and send a Booking Change Request advancing the checkout date. Then immediately lower your maximum stay.
