The major problem is your listing that rates below Airbnb's Standard of 4.8 and your below, I can see most reviews are good but especially when you don't have a lot of reviews 1 or 2 angry Guests realy hurt.
To fix
om the low listing nuke sure you fix all issues. Look at your Category ratings along with the negative comments because like check-in just has the low score.
Once you have addressed everything. Set an Airbnb Custom Promotion with the 20% Discount Airbnb will perform some free marketing.
Just for this rental turning on Instabook Airbnb Search will push higher, I usually increase my notification days so I have time to vey. Remember you can turn this tool on and off.
Regularly update your listing The Airbnb computer reads date modified to determine new or old. Updates can be major or minor the date changes.
For your new listings
1. Review to prevent similar issues as first.
2. Use Airbnb New Listing Discount
