Kona Mtn. Refuge a.k.a Swell was fantastic! From the stylish decor and comfortable lanai with AMAZING views, it was easy to spend a lot of time just hanging out there. Nearby tasty restaurants and gorgeous beaches/snorkeling are so plentiful, that driving into Kona isn't necessary, but still near enough to do if you really desire.
Shaheer was fast to communicate when we had a small issue and rectified it quickly. He also gave me free reign to pick as much ripe guava and starfruit as I wanted from their yard, which was delicious!
If you like cats, handsome Papaya has a 6th sense about when you're available for pets. He'd appear and hang out while we ate breakfast on the lanai and again at sunset to lay in the hammock with you. Though, I'd expect if you aren't a fan/allergic he'd leave you alone.
As with other islands, Hawaii has loud invasive species challenges, so be prepared for noisy chickens and Coqui frogs. This will be the same wherever you go on the island and not the fault of Swell proprietors. Bring earplugs if you're bothered by this sort of thing.
It is a very spacious studio and you could probably have a third person on the couch, but it's best for a couple.
