Hi Kim,
You're doing a great job and learning the hosting game! Hang in there!
The old reviews will carry less weight as you get more 5-star reviews. You'll just have to be patient until then.
It looks like the areas you scored lowest in were cleanliness and accuracy.
Do you feel that you've fixed these areas now?
We (my cleaner and I) had to come up with a checklist. When we're done cleaning, we "inspect" to make sure we got everything on our 60-something-item checklist. Everything from checking the beds for lint/hairs to ensuring the ice cube tray is filled.
A lower accuracy score means there's something surprising people. Either your listing makes a promise about something that isn't there or isn't as nice as promised, or it doesn't make mention of something that's disappointing (think of any sights, smells, noises that could be off-putting).
If you've already made changes to both these areas and your reviews are just catching up, then just keep at it. Ask an honest friend if there's anything they'd suggest. Guests can also be a great help if you ask. Sometimes we're blind to the flaws in our beloved homes. 😉
