Reading your reviews price isn't your issue. The few beginner hiccups many have for cleaning or minor issues.
What is negatively effecting you is minor challenges accessing and parking. You are actually shooting yourself in the foot not just identifying and lowering your price to the point that you are attracting Guests who shouldn't rent your property.
Identify who is your proper market based on your area. Determine the average price of similar listings. Review their descriptions maybe you have something you didn't mention and you should.
Since it has been complained about more than once speak about parking and the access way. Take clear pictures of the stairs and caption entry. Not everyone will have issues the irritation seemed more because surprised. Nobody likes a negative surprise
