@Georgi702 Being one of the cheapest places in the area might help attract bookings, but it doesn't result in better ratings and reviews. Unfortunately, a low rating early on can have an outsized impact on a listing's appeal to potential guests. The effect is autocatalytic - the better guests avoid lower-rated listings, so instead you just get booked by the worse guests, who in turn leave worse reviews and make the rating go down more.
The one point where you can really shape your future reviews is when a request comes in. Then, you have a 24-hour window to discuss the ins and outs of the home with your prospective guests, make sure their expectations line up with reality, and possibly decline if they don't seem enthusiastic enough about the place to be likely to leave a good review. Obvious downside is that declining requests in a slow season means more vacancy and less income. Not ideal for your situation.
A few minor edits might set your listing itself on a better path. For one thing, the very opening of the listing shows the wrong specs: "4 guests, · 2 bedrooms, · 0 beds, · 2 baths" That should show as 2 beds; be sure you complete the Listing Details editor to get all the accurate specs in there. According to your House Rules, you allow smoking. This might be appreciated by the minority of people who like to smoke indoors, but it will be off-putting to the larger portion of the population who finds the odor unpleasant, so it might be worth reconsidering. And while your written description should be upfront about the fact that the home is rustic and unrenovated, you might be able to identify a niche for whom the house's unique charms are particularly appealing and lean hard into that with your word choices and aesthetic improvements.
No doubt though, you have your work cut out. A lot of people overestimate their ability to relax into the vacation mood when they're in a house full of someone's old stuff, and some of it probably needs to go. I would get the workout equipment out of the bedroom ASAP, find some affordable secondhand patio dining furniture in time for the return of BBQ weather, and invest whatever you can in window coverings and other decorative textiles to liven up the home feel more like a place of fun and recreation. At the moment it seems to be more of a museum to your father's memory, and guests are going to be subconsciously influenced by that in the wrong way if they're trying to enjoy a family vacation.
