@Paula1563 Usually when a guest says that a listing is in an unsafe neighborhood, it is based on the guest's perception, rather than fact. I have no idea what made you feel it was unsafe, but often it is that the guest saw some drug-dealing or prostitution going on out on the street, or even that it is a neighborhood that is largely populated by a racial or ethnic group that the guest perceives as "dangerous".
The "unsafe area" statement from guest usually doesn't have to do with the guest's actual experience of being harassed somehow, but simply their own beliefs, which is why such statements are irrelevant to the listing and the host, which is what a review is supposed to be about.
The guest also bears some responsibility to research the area of a listing to see what information there is on it. This is similar to guests booking a vacation in the tropics and then complaining that were lots of insects. Of course tropical areas are rife with insects- that isn't the host's fault or anything they have control over.
My daughter once lived in a part of the city where she had to pass through an area quite populated with drug addicts and prostitutes when walking home from work. I expressed concern about this and her response was "Mom, they're just crackheads, they don't bother or even pay attention to people who are just walking by."
My concern was due to my own ideas, rather than the reality. It's one thing to state how you felt, but another to state your feelings as fact.
