@Judy525 When one of my daughters was a kid, some of her friends' parents would say to me "I just love it when Z. comes over to play. She always organizes and cleans up my daughter's room. You must be so thrilled to have a girl like that."
Meanwhile, her own room at home was always a disaster, with clothes and books and art supplies ankle deep you had to wade through.
When I asked her why she cleaned up her friends' rooms and not her own, she told me that when she cleans her friend's room, she feels like it's her room and all the stuff there is hers- it was like playing a fantasy game.
There are all sorts of unimagined reasons why someone might behave differently in one place than another, and leave a totally different impression.
One thing to watch out for when it comes to "good" reviews is that when you read a review that just says "Great guests!" or something similar, without any real information, if you click on the host's profile and then on the review pages of the guests he's had, you'll often find that the host leaves the exact same "Great guests!" for every single guest.
I totally dismiss those reviews, because the host may not be being truthful or just thinks that as long as the guests didn't burn the place down, they deserve his obviously canned all-purpose review.
