Actual location much different than listing

[Korey7]

How does the “approximate location” get put in a listing (i.e. by the host, by Airbnb, or by some Google algorithm)? I’ve stayed at a lot of places before now, and typically the actual location turns out to be within a few blocks of the approximate one displayed before booking. Today I got a confirmation and the place is 14 blocks away from the icon displayed on the Google map in the listing. This being the center of a major city that I’d hoped to walk in, is a big difference. I can cancel this if need be (my trip is two months away), but I don’t want to make this mistake again, especially with one I can’t cancel.

@Korey7 they do it by postcode, but if hosts don't check they are sometimes wrong.

I had them site the pin in the map by hand so it was correct.

Dialogue with the host would help, if it is not clear in the listing.
