Hi John, I find this whole review culture of everything from dining and purchases to accommodations and medical care an interesting sign of the times and I do usually find the reviews helpful, positive or negative. Reviews in this shared economy experience are the backbone to the safety of the host and the value for the guest. In my opinion, not being happy with a guest ranges from annoying to horrible. Annoying can be a mismatch of the guest with the host, but horrible many mean major property damage or even threat to the host.
Vague or general reviews are not helpful to either. I ask myself if I would want to host a guest again and if not then my review spells out what was problematic. Now sometimes what is problematic for me with a private room in my home would not be problematic in an entire house listing. Important to realize that. Sometimes the issue is ignorance on the part of the guest or host and a private message would be helpful. I also understand that hosts are afraid of "retaliatory" reviews which are in part mitigated by the simultaneous publishing of the host and guest reviews. If there is a negative review a professional response about the situation is more important than the review itself. Not a perfect system, but I would not be able to participate in this business without it.
