Is there a beautiful graffiti spot? If so, post it.
You're using Instant Booking so you don't have a chance to communicate with guests prior to the reservation about the neighborhood. You may consider removing IB and specifically asking if they are aware that this is the hood, that you cannot control that this is the hood, and that ABB will ask guests to rate the hood which is impacting your overall business goals.
