@Chris14432 I notice that your listings all describe the community as (in your own words) a "5 Star Resort." That strongly implies a different degree of luxury than you're offering. And while the word "rustic" might seem to speak for itself, it's not very useful as a description because it means something different to everyone.
Glancing at the more critical reviews, none of them mention the lack of room service or a maid. The comments tend to focus on problems with the internet, the lack of hot water, and physical maintenance issues. It doesn't sound like these people were expecting more amenities than you advertised - they just felt that some of those amenities were in a state of disrepair and not up to a basic standard. Several consecutive reviews mention that windows and screens were badly damaged, but your responses haven't indicated any intention to fix them.
I can't say enough what a bad impression it makes when several guests leave constructive feedback about the same home maintenance issues and the host doesn't respond. That makes prospective guests think that you're not attentive to guest's concerns and you're not taking enough care of your properties. Your best potential customers will find this very off-putting and book elsewhere, so the only people left to book are the ones who aren't paying attention and reading.
This is all quite fixable, but I think it's worth first taking a closer look at what basic things you can fix in the cabins. And then, overhaul your listing descriptions to reflect the recent changes and also more narrowly target the type of customer who's best suited to your offering. There's nothing wrong with being explicit about aspects that some people might find negative (such as the WiFi or lack of hot water) in order to set up accurate expectations. But at the very least, even in the most rustic cabin, nothing should be janky or broken.
