Quite honestly I leave an honest review of a guest once I have checked how the guest left the accommodation. @Brian1617 .
If the guest leaves an unfair review then so be it.
I can respond or if it breaks Airbnbs rules ask for it to be removed.
All my reviews are positive so I am sure most guests would see the one bad one for what it is.
Just post on the last day if you want and don't worry about it. Life is too short to spend so much time worrying about these things.
By the way, why do have a blank profile and no listing @Brian1617 if you are a host?
