My isting has dropped position

[Deborah-and-Tony0]

My listing used to be first on the first page - now it is half way down the second page. I have Superhost status which I thought gave my listing priority however those now on the first page are NOT Superhosts.

Can anyone suggest why my listing has slipped down and is there anything I can do to lift it's position? 

Thanks in advance.
