@Andrea5943 a few thoughts
Your check in/out times mean you will need to block a day between rentals. Fine in low season but it means you are unlikely to get back to back bookings in high season
2 night min stay seems short for such a big place. Our 3 nights may lose us some bookings but we don't like cleaning.
The fines in your rules will not be collected by Airbnb so you are possibly putting people off for no good reason.
The rules feel excessive - But I don't know your market well.
The cleaning fee is very low relative to the nightly price. Either increase it to encourage longer stays or remove it and add a few dollars to the nightly rate.
Finally search for similar properties in your area - Within reviews you probably need to be 5-10% cheaper but you can increase prices as you get established.
