@John2297 There's no point in dragging your evidence file into this thread. It's not my job to litigate your case - and seriously man, an attitude like that will damage your business far more in the long term than a review.
To clarify, I never said it doesn't make a difference. So does a butterfly flapping its wings, supposedly. You might lose Superhost status for one quarter, but so what? It's a little badge, like a sticker on grade-school homework - it's only worth whatever feelings you've invested in it, and losing it is not the DOOM and DESTRUCTION that the more histrionic hosts among us forecast. You already have several positive reviews pushing that one down, and seriously - even listings with a middling track records managed to get booked if their location and price are desirable enough.
Also, a single review can make an impact in any platform if it's visible to potential customers. It really comes down to the content. If customers see a review mentioning words like "bedbugs" or "hidden camera" or "sexual assault," you've got a huge problem on your hands. Unspecific negative statements don't tend to make a strong impression when weighed against more substantive ones.
If you are finding that your listing is suffering at the moment, though, you might consider having someone make some decent photos of it. Airbnb is a very visual format, and people tend to pay far more attention to pictures than reviews. Your place is probably very nice, but the current photos in your listing don't serve it well.
