The condo itself is nice- small, but it had absolutely everything we needed from cooking to going to the beach to a cooler we brought when hiking. Plus the shower was great!
The location is perfect if you want an outdoorsy vacation. Easy to get to volcanoes national park, beaches, south point and many of the best parts of the island. If you want something a little more city, you can drive around to the other side to spend the day in Kona.
The biggest problem is that the majority of the units in the condo complex are managed by a timeshare company, so a lot of the guests were pretty thoughtless. We were often woken up at 6am by people yelling across the parking lot and we could hear just about everything the people above us did. The pictures make it look secluded, but all the units are really close together and because you'll have the windows open all the time, you'll likely be disturbed at some point or other by yelling/loud conversations. If you're an early riser or there at a less busy time this might not be a problem, but even sleeping until 8 was not possible most days.
Overall we had a really wonderful time and the hosts were super nice and helpful! I definitely recommend staying here.
