When you start out you are in competition with others who have good reviews and star ratings, that is what guests look for first of all. You should lower your price compared to similar properties in your area (not too low!) and get a few reviews under your belt. Then you can raise your price to the normal average for the area.
Can I also suggest the following - you have lots of pictures of lovely trees, no one will click on your listing when the first few photos show the trees. Secondly, you need more interior photos - tidy up the beds etc as they look unmade. I am sure your property is lovely but think about how the guest will view the photos they see.
