This is the perfect place to stay if you're looking to explore more of Kona, surrounding areas, and the Big Island overall!
I stayed for 10 nights, and between the space itself, the lanai outside, and the phenomenal location (most evenings I'd walk to dinner somewhere in downtown Kona, walk to a beach to watch the sunset, and then walk back), you get a lot of value here.
For food, the fridge, microwave, and hot plate give you enough options to cook or store things if you want. The private bathroom was great as well, and fully furnished. In the main room, there's a new electric fan if you're feeling hot (but I think I only used it once, open windows created enough of a breeze for me and the tropical weather doesn't fluctuate that much). And for the digital nomad, I did some work while visiting, the wifi speed is great, didn't notice anything different from working here vs. back home.
Marc's an interesting guy and a great host; I enjoyed chatting with him and his wife during my stay, and took them up on a couple suggestions for places to visit (End of the World is a great hike and cliff-jumping spot, for example).
