@Bellanger0 safety is a big issue for guests. You have to remember that these people are going on a vacation. Not everyone understands what life in an urban neighborhood in Chicago is like, even if they watch the news. The city varies wildly. If you are totally unfamiliar with an area it could be a rude awakening.
That said, many times "unsafe location" means that there are non-white people living nearby. Its inherently racist, yes. I would just be painfully clear in your listing. This area is located next to X attractions. It has a walk score of X. There is some crime in the area so please use caution. Its a diverse neighborhood. Its not a great place to walk at night. That kind of stuff.
Or maybe consider doing a landlord situation instead of ABB. We have a gorgeous condo in New Orleans that we use as our own vacation spot but would not open it up on ABB. Why? Because its New Orleans. We have seen open air drug sales, people getting in violent arguments, women soliciting, etc. Our condo is not in a bad location by any means but that is what the city is. Heck we just had packages opened and the contents stolen after being on the doorstep for an hour. One guy who lives in a million dollar place down the street had is car broken into 7 times in the last 2 years. People do not always understand the realities of urban life. Likewise, some locations are not suited to host strangers who you can't vet to ensure that they understand what you have to offer. Good luck!
