Reviews for a new listing are treated no differently than reviews for other listings you may have received. If you have not received a review it is because the guest has, for one reason or another not given one. They do have 14 days, so be patient!
Only reviews for you new listing will be displayed in the review section but, just below the review section and above the host profile information there will be this notation....
The person looking at that listing can click on that box and see whatever past reviews that host may have and what listings they may have been given for!
Airbnb do this so a host cannot escape a bad past....they can post a new listing but their past reviews will always follow them!
