Bottom line: this was a spacious, comfortable, and clean studio; the location made a great base for exploring the big island. I had an amazing stay, and definitely hope I can return!
I thought I would provide a few more details about the space based on my experience.
This is a private studio with a separate exterior entrance. There is a firm queen size bed, as well as a couch and large overstuffed chair. There is a private, en-suite bathroom. The kitchenette is well stocked with basic dinnerware and cookware, as well as several small appliances (coffee maker, electric kettle, microwave) and a large apartment sized refrigerator. There is a window unit air conditioner, but I found I didn’t need this as evening temperatures were comfortable for sleeping.
Additionally, beach towels and a beach chair were nice touches! These extras really made my time at the beach more comfortable.
Kobayashi was very responsive with excellent, clear communication; he was readily available to assist with any needs.
The location of the studio was an ideal jumping point for nearby beaches, as well as towns like Hawi and Waimea. A car is needed for exploration.
I would not hesitate to stay here and hope to be able to return!
