Does moving your approx location map a bit help or hinder?

My friend is near a major metro area but is located on the other side of a river. The location is not always coming up on searches of the major area. Would moving the approx location to a bit into the river help or hurt? Would it make the listing more visible to the folks looking in the metro area?

Its a double edged sword!
It may get them more bookings, but could also mean more negative reviews with guests complaining that location is not accurate which can be a death sentence to a listing!
How long does it take to cross the river, and how much more expensive or stressful does it make the journey?

Its the nj side of the hudson river. It is literally 10 mins to midtown ny. I am proposing the location marker be slightly into the river… the actual location overlooks the river fyi
