Vacation rentals in Belltown

I want to make sure the blurb is accurate, but I’m not finding reliable, widely-known information about a town named Belltown in Maryland. Could you confirm the county or nearby city (or share a link to the town’s page)? If you’d like, I can draft a neutral 2–3 sentence blurb using generic, widely accurate statements about small Maryland towns and you can customize it once you confirm the specifics.
