Hello @Matthew1661
Unfortunately Airbnb when they updated this community a few weeks ago decided to remove our access to be able to see host and guest profiles on here including links to listings so we can't see your listing or the review in question so it's hard to give you proper advice.
I'm sorry you had a bad experience with a guest.
Just to reassure you one of my first guests gave me a one star throughout and left a review full of lies. Yet within the first quarter I became a superhost as it didn't stop people booking with me. And six years later I am still as SH.
I think although some guests do check your reviews many do not and if the rest of your reviews are great you will still get bookings.
It's more likely to be a combination of factors that are affecting demand for your listing including
1. Airbnb's summer release - changes to their website left many hosts with a slump in views and therefore bookings
2. There is a saturation of STRs in many areas with too many STRs and not enough demand
3. You may be in low season.
4, There is a recession in many countries as utility and food costs rise leading to falling demand for STRs
Please don't lose hope. Here are some tips
1, Review your listing photos and content to make sure it's written/photographed with your target market in mind.
2. Review your pricing - is it in line with your local competitors
3. List on other relevant STR platforms
4. Set up your own website/FB page and invest in advertising to drive traffic to your own marketing channels so you can take direct bookings.
Good luck.
