With the new rating system we were concerned that we'd start seeing less than our normal 5 star reviews.
What we did was set up a canned reply for people who are good guests we'd recommend and try to put the words "Exceeded Expectations" into their heads.
It says:
"Thank you for leaving everything so clean! You definitely earned a five star review from us and we hope to have exceeded your expectations as well.
Please come stay with us anytime and travel home safely!"
For guests we won't recommend, we say something to the effect of "We hope to have exceeded your expectations and that you get home safely."
So far, it seems to have worked as we now consistently get 5 stars. (That and we deserve it 🙂 )
Just a tip for others.
