I stayed at Wendy's place in early April 2018 with my wife and 14-year old. The place was as-described, clean, and fully stocked with everything you need to golf, snorkel, board, whatever. The location was right next to a small public beach that was great for sitting and enjoying a good book (not really water safe to swim, wade, etc. as it's pretty rocky with rough waves). But hard core surfers and boogie boarders would enjoy it. Or you can just park under a palm tree, drink wine, and enjoy the view.
The condo itself had a great area right outside the pool with lawn chairs that provided some cool tide pools and fabulous sunsets. It become our favorite part of the property. The pool itself was small and in need of a cleaning. But from the grumbling I heard from the full-time residents this was not the norm.
Wendy herself was great about replying to questions right away. You will not find a more responsive host. And the candy treats were great - thank you Wendy!
The place is "cozy" and at times the three of us were maneuvering around each other. But if you're traveling as a couple, or even with one kid in tow, it's great. It's walking distance to good eats and great views (in Kona itself). It's also central if you're planning (as we did) to check out both the north and southern parts of the island. It was roughly 2 hours drive to Volcano National Park to the south, and roughly 90 minutes if you want to hit some of the great resorts and beaches in the north. Oh, and the AC works...it definitely came in handy a couple days.
You should also know that Ali'i Drive is a busy street with traffic at all hours. So if you stay on or near Ali'i (and if you want a room with a view it's a must) the noise comes with the territory. The first night we were there it was definitely noticeable, but as the days went on it became white noise.
Overall, great spot and a great host!
