Delphine's father Guy met us on arrival, was hugely helpful with all our (family group) logistics of baggage and briefing on the house. He's an extremely warm, friendly, welcoming person who took as much time as one would wish sharing his encyclopedic knowledge of Hawaii--especially the local beaches and 'places'. He made himself available to us but we didn't need anything as the house is extremely comfortable (very comfortable bedrooms/bathrooms) and 'wrap-around' lanai.
House in a quiet setting with very beautiful 'private' pebble beach at the bottom of the hill that we could hear from the lanai. Host have a nice supply of snorkeling gear to use (nice!) and a good bunch of cute geckos outside the house.
Location is a bit of a 30' drive from Kona but we found the access to the beaches down to South Point is great--and a more 'true Hawaiian' experience. Besides beaches, access to Volcano Nat Park, Hilo (and probably the Mauna Kea observatory which we didn't make it to..) is good.
We would love to return to this great place!
