Mandy & JR were great hosts - really thoughtful and helpful with recommendations. We had told them we were going to be checking in late because of our late flight and they made sure to leave a light on and make the check-in process easier for us. When we were going Hapuna beach, JR was kind enough to offer us all the beach supplies we needed to make a successful beach day (ie beach blankets, chairs, umbrella, cooleretc). The place is less than 10 minutes into Kona town, about 45 mins to Waikoloa village.
The place is more spacious in person than in the pictures, and you really can't beat the view. It was such a beautiful sight to be waking up to the ocean every morning. The lanai is great to sip some coffee and watch the sunrise (or sunset) - you might even see their very cute cats doing some adventuring of their own on the rooftop. Overall, it had everything we needed but we didn't spend a lot of time inside because we were too busy exploring.
One thing to note is that there is a flight of stairs that leads up to the guesthouse, so if you have someone that has difficulty climbing stairs or heavy luggage that need to be brought upstairs, this may be a slight issue. Also, there is some netting on the top part of the walls (ie not a solid wall) and you'll probably be sleeping with the windows open for a breeze so the animal/bird noises can be a bit loud at night. I'm a very light sleeper and the first night was rough and I had buy some earplugs. By the end of our stay however, I had gotten accustomed to the sounds and I had no issue knocking out without earplugs after a long day of adventuring. So if you're a heavy sleeper,have some earplugs, or really tire yourself out, this is a nonissue.
