This is a unique property that has some terrific pluses, but also some minuses to consider.
The home is a large and attractive with comfortable beds in both bedrooms, two nice bathrooms, and a very comfy sofa. The kitchen is large and well equipped, and there is a nice patio with a beautiful view.
The property is on a huge lot filled with gorgeous plants and trees. It is like living in a rainforest. That plus the abundant supply of gorgeous little dogs and a 100-pound turtle you can feed really make it special.
Most of all, Karen is a true super host who will go to no end to make your trip a special occasion. She sent us a huge amount of advanced info about places to go, itineraries, with photos, etc., and answered all our many questions during our visit. She makes available abundant snorkels, fins, boogie boards, beach chairs, towels. As we were arriving very late at night, she even went shopping at Costco for us before we arrived, only charging us the cost of the groceries we bought.
But, there are some important downsides you should consider before booking this place. First, it is noisy. Lot of street traffic noise throughout the day. For at least one of the people in our family of five, that alone would probably be a deal breaker from our coming again.
While we were there, there was also an extremely noisy frog (or frog family?). Unlike the street noise, I think that can possibly be dealt with, so if you book here you may want to ask about whether that has been resolved.
In addition, the pool is small and not very warm, so it's not a replacement for a resort pool.
There is no laundry on the premise, though Karen will wash and dry your clothes for a reasonable fee.
Finally, the location is convenient in certain ways (near the airport, Costco, Walmart, Kailua Kona) but a long drive from what I consider the two most desirable tourist locations on the island -- near the Kilauea volcano on the Hilo side and in the Waikoloa area on the Kona side. If you on'y want to stay at one place that is somewhat centrally located all week, then this works out well, but you will probably be driving every day to do things.
In summary, if you want a large, centrally located place at a very reasonable price, with an amazing host, this is a terrific option. But if you want a quieter resort-like experience, you may want to choose elsewhere.
