@Inna22 Your most recent review has a lot more detail in the feedback than just the trash bags and toilet paper. The thing that immediately jumped out at me was that the guests were not a family but rather a "company retreat," so it sounds like some of your multi-bed dorm rooms were being shared by adult colleagues rather than close friends or relatives. Probably no big deal if the company was Cirque du Soleil, but for most professionals I can imagine the awkwardness of that sleeping arrangement would put everything else in a negative light.
I get the impression that up to a certain guest count, your unit feels like a luxury home, and beyond it it's something more akin to a youth hostel. Of course the context of a pandemic adds an extra layer of complication to people staying in close quarters like this (really, it's unconscionable that an employer would subject their staffers to that arrangement, but it's not your fault as the host).
What's up with the garden gnome and bathroom figurines that the guest found offensive? Those aren't visible in your photos, but without a cautious Host Response it would be easy for a prospective guest to conclude that you're a creepy racist.
