We really enjoyed our time at Kelly's place. Her AirBnB was large, comfy, and nicely-furnished. It's a very stylish space and had everything we could need.
Rented a board from Kahalu' Surf and Sea for a week and was able to hit the morning waves before the tons of surf schools set up later in the day. It's merely a few hundred feet from the condo to the surf and probably the Big Island's best snorkeling. No need to find parking! If you go up to the sea wall between the two lifeguard stations, you'll probably see a lot of sea turtles each day at high tide without even having to get in the water. We'd see ~ 6 small honu right at the wall whereas any time we've snorkeled, we've only seen one or two.
We got a nice jog in every morning and enjoyed the sunset every night. The pool was surprisingly under-utilized so that was a nice way to cool down and also get exercise.
Great places to visit in the area include Da Poke Shack, Kealakekua Bay (and kayak rental from Ehu and Kai), and the manta ray night snorkel in Keauhou. We also recommend Mauna Kea, Waikoloa, Hapuna Beach, A Bay beach, Pineapples in Hilo, and Volcanoes NP. You can't go wrong with this location. In my opinion, it's lots better than being closer in to town.
