@Mike2510 Hmmm....this sounds like a "Category" issue. Airbnb determines your category, not the host. You'll see if you have been assigned a category by Airbnb on your listing page/Property & Rooms Section. If you don't see anything under Categories, you'll have to contact Airbnb to get them to add "Beachfront" to your Listing Category. Here is a screenshot and Help Article:

Your Listing should show "Beachfront" here:

Hope this helps. Let us know how it goes!
