A place that turns out to be right on the noisy highway won't have a single review that points this out. Only "great for early risers!"
My strategy is to just not review if my review wouldn’t be positive.
Been using Airbnb quite a lot in Europe the last few months though and I have generally found some very high quality and accurately advertised listings — only had 1 that really fell below expectations.
I encourage anyone to post real honest, negative reviews if the experience is indeed bad. Airbnb seems to do a good job building the system, and I feel guests are protected quite well, from a host’s perspective. Honest reviews help good hosts, and I would think I’m one of them :)
The customer service agent refused to remove the review.
