Firstly, the cottage is located at strategically close to Kona - not in the city but not out in the boonies. It served as an excellent base for my expeditions all over the island.
Secondly, the cottage is well-maintained. It is spacious and has all basic amenities (no dishwasher if you care for it, I don't). The ceiling fan is pretty good for a bit of cooling in the nights. There's another floor fan if you want more cooling. The cottage is also located in the back of the property, which gives plenty of privacy. The bathroom is a bit small and doesn't have a bathtub (if you care for it, I don't). There are automated lights along the path to the cottage, ensuring full visibility even at night.
Thirdly, Ruth is a fantastic host. She was extremely accommodating of my weird scheduling and is very considerate and helpful. She offered plenty of help with stuff and was very pleasant to chat with. Just be helpful to her and keep her posted on your check in and check out schedule so that she is aware of your arrival and departure.
Lastly, buddy is the coolest, happiest and the most welcoming dog I have ever seen. He is so excited to see guests. I miss him already.
I have no hesitation in recommending this Airbnb for couples or small groups. Just a fantastic experience all round.
