I am not sure how this would lead to better reviews @Wendy684 ?
I do explain the rating system in my guest book and follow up with guests during their stay to check to check that there are no issues.
I also ask them to let me know if they feel that anything isn't as described in my listing and say to let me know if any amenities fail to work.
If you have had two recent guests mention cleanliness issues, it's probably worth asking a friend to check the place once you have cleaned it, in case there are issues you are missing.
I also follow up with guests who mark me down on ratings and ask them to help me improve by giving me feedback on specific areas they feel didn't come up to scratch.
Having had a quick look at your listing, if it is still as shown in your photos, I would try and declutter both your kitchen and bathroom. Sometimes people see clutter as somewhere not being clean, even when this is not the case.
