Shared room with colleague on business trip - Cali king size was perfect - two large grown men happy to have huge empty space of bed between us. Huge bathroom with great shower. Provided ample shower and beach towels for us. Had spacious backyard patio area with grill, laundry machines, clothes line, and projector/screen connects to laptop via HDMI cord. Host recommended beautiful snorkeling spot we wouldn't have otherwise known about.
Very close to everywhere you would want to eat, drink, and do water stuff in Kona. Airport is approx 30min north on highway in average traffic. Magic Sands beach is approx 15min drive from Jessea's and was our favorite non-surfing beach. Beautiful. It had white sand and a very entertaining shorebreak we enjoyed much more than Hapuna Beach (which we had visited day before and is 50min drive north). Not to mention all the good places to eat (Broke Da Mouth Grindz, Da Poke Place, Umeke's) are all in Kona (not up north) close to her place.
Info for surfers: I rented a 6'4'' HaydenShape shortboard from Kona Boys (true to website price details etc) who had a wide selection of boards in the quiver and were helpful in recommending local breaks and important associated details. I spent most days at "Pinetrees" which is just south of the airport (20-25min from Jessea's) and has multiple breaks including an area for beginners. Best time to surf is high tide but beginner area safe (no exposed areas) even at low tide. Other places to check out on the West coast are Banyans (maybe just to watch unless you can get a local to take you out - single peak split by some of the better local surfers) and Lymans. These last two spots (15-20min from Jessea's) are your best bets if surf's up (Pinetrees starts closing out, doesn't hold larger swell). Aside from these rock-bottom breaks, there is a beach break at the old airport that is very easy to access with ample parking. Mostly spongers here but also some surfers.
