I don't think you can update a published review, Rachel. It's done. Once you have a few reviews for your place under your belt, you might not be so eager anymore to get reviews asap, so maybe just wait a week or so, see if the guest actually writes you a review (Airbnb will prompt you if they do) , and after you had a chance to throroughly check the place, write your review then.
I don't write reviews on guests anymore if they don't write one for us, unless it is something blatant I would want to let other hosts know about. the little stuff, like a broken wine glass, a general sloppiness or carelessness, I decided to just let it go, it comes with the territory....
@Rachel124, I just tried to look up,your listing, it's not there. Did you take it down?
