@Laurie939 people cannot retaliate with reviews as they are blind and seen by neither side until both are posted (or if only 1 side reviews then after 14 days).
If you do not review honestly then, as a guest, when I look into a poor review of you as a host I cannot go and see what you thought of the guest. Hope that makes sense!
The ONLY risk of leaving an honest review is that, the the guest has left you a glowing review, they can ask for their review to be deleted.
Also it's good to see you have 4 star reviews - The pressure and stress of a perfect set of 5 star reviews is immense!
