HIGHLY recommend staying here! This place was exactly what we needed in terms of proximity to beaches and Kona town, cleanliness, kitchen amenities, and entertainment. Rosalba even provides snorkel gear for you (the non-basic kind too, where you don't have to physically blow out water that gets into your snorkel), which saved us some money since we didn't have to rent.
I can be a stickler when it comes to cleanliness, especially in the bathroom, but the entire place was so immaculate that this wasn't a worry at all. I felt so comfortable and clean the entire time. A/C was only in the bedroom, but it worked extremely well and we did not feel any discomfort whatsoever!
Rosalba was really sweet as well :) We only saw her once during our stay there--she came by to give us some chocolate to apologize for the drilling that she was doing upstairs. In reality, we didn't hear any of the construction work at all!
