My wife, 3 year old son and I had a great stay at Liz's ohana. The great location, a short walk to Magic Sands beach, an not far from downtown made for a nice week in Kona.
There were some great perks like 2 sets of snorkel gear, beach chairs and mats, 3 boogie boards and ample towels to make beach days possible without renting anything.
There was a fully equipped kitchen and a small gas grill on the deck which we used several times. We cooked in quite a bit and really appreciated things like a coffee grinder, blender, rice cooker/crock pot, Brita water pitcher, Tupperware and getting the morning paper each day left outside the kitchen door by Liz or Robert!
The stay was peaceful, the location is very quiet with minimal road noise from Alii drive below. Liz and Robert were very respectful of our privacy, yet always accessible if we needed anything. Keep in mind that you are staying downstairs beneath their home, but it felt very separate. The main bedroom was large enough that we set up the single futon from the entry/living room in there for our son.
I'd also add that Liz was very responsive and easy to communicate with throughout.
Mahalo!
