For context: I live in a two story house where the setup is basically split into two separate living spaces. My landlord lives downstairs, which has its own kitchen, dining area, bathroom, etc. Upstairs is where me and my two roommates live, and we also have our own kitchen, dining space, bathroom, and living room. During the week, everyone stays in their own areas and it works perfectly fine.

The issue starts every weekend when my landlord’s girlfriend and her 10 year old daughter come over.

The girlfriend completely takes over our upstairs kitchen instead of using the fully functional one downstairs. She cooks, leaves a mess everywhere, and despite multiple polite conversations asking her to clean up after herself, nothing changes. Meanwhile, her daughter is constantly hovering around everyone, rummaging through our stuff in the bathroom, and generally making the upstairs feel less like our home and more like we’re hosting uninvited guests every weekend.

To make things worse, the girlfriend is also an extreme snoop and gossip. She’ll randomly whisper to my landlord while looking around upstairs, which honestly makes all of us feel like we’re being judged or talked about in our own living space. It’s created this uncomfortable atmosphere where nobody can fully relax when she’s around.

The entitlement is also what's getting to me about her presence. At one point she saw my car in the driveway and asked “who was in her spot” despite the fact that she doesn’t even live here or pay rent.

At this point she genuinely feels like an invasive species.

We’ve tried being direct, polite, and passive aggressive. Nothing works because she seems to think the upstairs is now an extension of her boyfriends home. So… does anyone have any ULPTs to subtly encourage her to stay downstairs during the weekends?

I’ll admit there’s a chance I’m missing some perspective here ... maybe because my landlord owns the house, it’s unreasonable for me to expect them to stick to the downstairs kitchen. But considering the house has functioned as two separate living spaces the entire time, it’s getting really hard not to feel like our boundaries are being ignored.
