Hi @Danielle-And-Justin0
I'm not sure why I'm answering really because I really suck at writing reivews like this and frequently come to these boards myself for very similar advice.
Howver, it is definitely much easier to write a review when you are distant and detached.
One great piece of advice hosts give - espeically @Sarah977 - is not to think of it as a negative review just think of it as an honest review. It doesn't have to been judgy or nasty.
other people will do much better than me, but you could say something like, XX and her family adn very young children stayed for xx days. From start to finish they were friendly communicative and followed my house rules. ( if this is true) Unfrotunately, after checkout, a great deal more time than usual was needed to clean and prepare for the next guests. I would welcome xx again, if they were a more careful and considerate about cleaning food and debris from walls and soft furnishings" ( that last bit might be a bit much, but it makes it clear it was more than just a few crumbs under the table, food splashed up a wall and not cleaned up is not acceptable IMO. and nor is playdoh everywhere and certainly not a torn couch. I have 3 maniac sons ( adults now) and I would never leave a restaurant high chair like that let alone someone elses house)
I'm sure clever and more diplomatic people them me will have better ideas - just read them all and pluck out what you think suits. And definitely mark them down on cleanliness.
You could try claiming for the couch - but that will almost certainly result in a bad review. Or you could buy a removable sofa cover that covers the tear adn has the benefit of being machine washable.
Good luck!
