Lots of cities and resorts are suffering from over saturated markets coupled with falling demand because of the recession @Anthony1658
Have you looked at supply and demand for your sort of listing in your location?
I would say in your case you also have some very low ratings and comments about cleanliness and the accommodation not being large enough for the numbers advertised that are likely to be putting some guests off. And of course lower ranked listing don't appear at the top of Airbnb's rankings.
You also don't seem that you have responded to these reviews to help address concerns for future guests.
It's probably worth looking at where you are getting lower reviews and how you can address concerns around cleanliness, there only being three bedrooms but having a listing that sleeps twelve, issues with the toilet etc.
