Vacation rentals in Elm Beach

I can’t verify a place officially named “Elm Beach, New York.” It may be a neighborhood, local name, or a typo. Could you confirm the exact town or provide a nearby city (e.g., Long Beach, Montauk, Fire Island, or another NY beach town)? If you’d like, I can draft a 2–3 sentence blurb for a real NY beach destination or adapt it once you confirm the correct location.
