It simply isn't true that you can't post a negative review on VRBO. If it's downright uncivilized with gratuitous profanity or something like that, yes, I'm sure VRBO will and should pull it. I am a homeowner and people have said things on my site that I have the right to refute. It's tough judging something through reviews because it is a fine perspective, not a full one. And we're all very different. And some people just can't be pleased, in this life.
