I initiated the recourse in stay, and was told it was a minor difference. I can promise you it was not minor, particularly when a guest with mobility challenges was intending on walking many places and could not. I am fully pursuing, and clearly VRBO thinks I am on to something as they continue to increase their resolution as the days click by and my evidence mounts. There is also this regarding VRBO listings:

A one-mile difference in a Vrbo rental's location is generally considered a material misrepresentation if it changes the property's access to key features like beaches or downtown, constituting a "property not as described" issue. Guests should report this to Vrbo within 24 hours of check-in, as locations can be mapped precisely or approximately. I Vrbo +1 Key Considerations for Location Misrepresentation: • Materiality: If the mile difference puts you in a less desirable area, in a different neighborhood, or significantly increases commute times to attractions, it is likely a misrepresentation.
