Hello @Heather325. Can you see it from your account when you're editing your listing or are you checking it from outside, e.g. not logged in just like a potential guest? In the latter case, the location is never shown precisely.
If the first applies to your case, then check in the listing edits if you can change location on the map (by hoovering it 'below' your pinpoint).
I am having the same problem - my pin shows my place in the middle of the ocean and I can't get it to budge (yes in edit mode). I have sent 4 emails to Airbnb and can't get a response. Anyone know how to solve this?
