Being honest I think you need to focus on improving the look and feel of your property so it feels more homely, decorated and co-ordinated with your target guest in mind.
Then you should get someone with an eye for photography to retake your photos .
I'd also suggest you describe your listing highlighting amenities/type of guests it's suitable for and why and attractions and amenities in your location. Focus on answering the question - why should guests stay with you?
Finally your lower ratings would give me pause for concern.
