@Dona-and-David0 Your listing is off to a great start. The description is both perfectly thorough and a pleasure to read. Your village is a place I'd never heard of before, but you've sold it to me as a great place to visit, and the photos of the scenery are lovely.
One thing about that though: you've advertised lots of fun summer activities and illustrated with some colorful autumn photos, but right now it's January. I don't think people planning a rural getaway in your area in the next months are thinking about swimming and kayaking. And while families and large groups often plan months ahead for the summer breaks, your hut only fits solos and couples, who tend to be more spontaneous. So if you're eager to get your first guests, I think you should focus on advertising the spot as a winter destination. Keep the summer stuff in too, but foreground everything about winter sports and activities, rotate in some seasonally appropriate photos, and show the home at its most warm and cozy. Even if you don't have a fireplace or sauna, some interior shots bathed in soft warm light will touch on the vibe people in the nearby metros are searching for.
Now we need to talk about those House Rules. You've clearly put a lot of thought into what you expect from guests, which is great, but my eyes glazed over halfway down that list and I could hardly be bothered to get more than halfway through through. This is not what you want. That list should be concise enough that people read it, so it's best to trim it down to the important things people must be clear on before they book, like smoking, pets, and unregistered guests. The other stuff, like remembering to use coasters, doesn't belong there - people won't remember it unless you go over it at check in and perhaps display a brief, printed House Manual. Everything concerning checkout (departure times, cleaning) is best covered in correspondence the day before, so you can take that out too. And those extra sentences where you convey flexibility on some rules (e.g. visitors) weakens the whole thing. Keep the flexibility under your hat, so you can offer it selectively to the guests who earn your trust.
Also, sorry to say, the effort you put into figuring out penalty fines for several violations was a total waste. Airbnb is not going to process those fees so they're just hollow threats. They're not known to be deterrent to bad guests, and they're really off-putting to the good ones, so it does you no good to have those in there. Your only real recourse for a rule violation is to end the booking, so rather than conjuring imaginary punishments, I'd focus on attracting guests who appreciate the place so much that they'll go out of their way to remain welcome back.
