Considered the price and location there really isn't that much more you will ask for. A few pros and cons like every other place.
Pros:
1) David is a nice host. He responses fast and is knowledgeable about the island.
2) Location is good. Walkable to two beaches and not far away from downtown.
3) David's place has a full kitchen, a full bath, water sport gears, and a laundry machine. Very convenient for a long stay.
4) David is a good photographer if you happen to be interested in some amazing shooting.
Cons:
1) No AC so it was really hot when I stayed. I don't think the big island is that hot in general though. David does have a few fans that you can use.
2) Walls are thin (like every other building in Hawaii based on my observation). This is an in law unit on the first floor and David's family lives next to/above us. We could hear them walking, talking, etc. and of course they can also hear us.
3) No dish washer. Not too bad but it would be nice to have one.
Overall I like this place and will recommend it😃
