Please allow us to edit or comment on reviews that we leave for guests in a similar way that we can respond to reviews that guests leave for us.
Here is an example for when this would be useful. I had an excellent guest stay that was pleasant and left my place in great shape. I left him a great review. He in turn left me a 3-star review (my only 3-star review out of 35 with a 4.8-star average) that was nonsensical and harshly critical. I wish I could comment on the review I left of him to let future guests know that, although he'll take care of your place, he'll likely leave a poor review.
