Hi Kamelia,
Your photos look very nice! The 5 night and 14 night minimums stays may deter some folks from booking with you. Also, the "similar listings" that appear for me on your page have a lower nightly rate than yours. I'm not famimliar with your area at all, so not sure how comparable these are to your place. To get going, I would recommend changing your extra guest charge to begin after 2 guests and/or lower your base rate. Then as you start getting more bookings, you can increase your rates.
Best of luck!
