@Alison435 I only see one review on your profile, and that is from a Dutch host. Is that the one? Because he didn't leave you a vile negative review at all- it's fine. Perhaps he sent you nasty private feedback?
You can report him to Airbnb and flag his profile. But it's odd that he has only a string of very good reviews, saying the place was clean and comfortable and that the host was great. Perhaps you just rubbed each other the wrong way?
I'd say just because the host used a tissue to wipe the sink doesn't necessarily mean the sink wasn't cleaned before your arrival- perhaps he just noticed some specks of dirt when he was showing you around and was dealing with them. I thoroughly clean my guest room the day before an arrival, but I go through just before the guest arrives to check for any dust, a dead ant, a stray hair, or anything that I could have missed or that deposited itself after I cleaned.
No, you can't edit a review once it has been published. Always be honest in your reviews so you don't regret what you said due to a bad review from the host or some nasty private messages. If you get a review which you feel is unfair, you can respond to it, but in this case, he left a good public review, so there's nothing to respond to. It's never a good idea to mention something in a response that was sent to you in private feedback.
It's not hard to leave a review which mentions the positive aspects of your stay, but also the things that could have used improvement, for other guests to know. So you could have mentioned that you found the bed uncomfortable, that the host acknowledged that he was aware of that, but hasn't done anything about it, but still praise the things you found good. Reviews where hosts or guests only talk about the negative, criticizing everything, while in some cases warranted, can make the review writer seem unfair and just a complainer. There's usually something positive we can find to say about someone or someplace, while still being honest.
