@Nina204 would you be willing to mention the sketchy area nearby, if only to point out that your property is *not* in that sketchy area (but that guests might have to drive through it)?
Good reviews are easier to get if guest's expectations match up well with reality.
If the guest has been forewarned "you will drive through (sketchy neighborhood) which is not very nice. But our listing is outside (sketchy neighborhood) and our neighborhood is very nice." there is a greater chance they will not mark you down for it.
Guest's generally don't like unpleasant surprises.
