As many before have written, Sylvia and Karen are very helpful and kind hosts. The night I arrived Sylvia made a fruit plate for me, and the next morning Karen brought me oatmeal and even gave me a ride back to the airport so I could pick up my rental car (which saved me a lot of $). Karen also gave me amazing detailed tips on what to see and where to go on the island, since I only had two days to explore ;-(. I followed these tips and that literally made my trip - amazing!
The only minor downsides I could mention is that the room can get a bit warm at night during hot weather, as was true in late Aug, and the space can get a little buggy. And as described, the shower is outside. But all of these things are pretty minor. The big thing is that this place is very nice, and I commend Sylvia and Karen in all respects. Mahalo!!
