Take a deep a dive into Airbnb and you'll see that the app allows you to sort rentals by property type. In addition to "apartment, "house" and "bed & breakfast," the site includes options to search for rentals tagged as "boat," "treehouse," "castle," "cave" or "farm." We looked to see what other unusual and unique rentals are available around Tampa Bay.

From the listing: "Rest up for the night in one of the 3 bedrooms provided in the home. The loft bedroom has a king-size bed and a sofa-bed en-suite bath, equipped with a jacuzzi tub, so you're ensured a relaxing and peaceful respite."

Of note: Geodesic dome houses such as this three-bedroom built in 1994 at 11955 119th St., Largo, have had a cult following since they first appeared in the 1950s. Proponents say they're roomier, more energy-efficient and sturdier than a typical house.

Price per night: $92

From the listing: "Escape to your private island within a stones throw of civilization yet a million miles away. Unwind with huge waterfront blue water views in a exotic resort that will take you miles farther than you actually traveled."

Of note: This six-bedroom "tree house" consisting of octagonal pods connected by covered walkways is on Jewfish Key, a small island off Longboat Key only reachable by boat. Luckily, the rental comes with a 25-foot pontoon boat the owners say can be used to reach eight restaurants within a half mile.

Price per night: $1,100

From the listing: "Located in the National Historic District of Ybor City, our award-winning little cottage stacks up perfectly with the charm of its older neighbors while featuring all the modern conveniences. Nicely tucked away from the energy of Ybor's renowned 7th Avenue, it's a short walk to plentiful dining & entertainment options."

Of note: If you're intrigued by the tiny house trend of recent years, but unsure if you could actually live in one, here's your chance to try before you buy. This home sleeps two and is 365 square feet on the first floor, with an 80-square-foot loft overhead.

Price per night: $105

From the listing: "Historic & Famous August A. Busch/Anheuser Busch/Budweiser Waterfront Intercoastal Estate and Compound now known as The Birds Of Paradise Boutique Resort. This Resort covers a whole city block on the water!"

Of note: Among the many notables who visited the compound back when it was owned by beer titan Busch were Marilyn Monroe, Frank Sinatra, Arnold Palmer, Farrah Fawcett and Aerosmith lead singer Steven Tyler.

Price per night: $3,933

From the listing: "This unique property offers a peaceful and relaxing farm-life environment. Whether you desire to sit on a rocking chair overlooking the land, play Foosball or Ping Pong in the game room, take a walk around to see all the animals including cows, donkeys, goats, chickens, rabbits and horses."

Of note: This property can sleep more than two dozen people and features a pool, basketball court and a tree house. The owners also offer a golf cart for getting around the property for another $20 a day. One note on the farm animals: "Guests and Guest's party assume full responsibility for any injury incurred from a farm animal. Guests may feed and/or pet the animals outside the fence at their own risk."

Price per night: $650

From the listing: "Enjoy the gorgeous water views from this boat as it is situated where the river meets the wide open Gulf of Mexico."

Of note: Of all the unique categories you can filter a search by in Airbnb, the most fruitful in Tampa Bay, perhaps not surprisingly, is "boat." You can find everything from this modest houseboat in Tarpon Springs to an 84-foot luxury motor yacht docked in South Pasadena that rents for $289 per night.

Price per night: $99
