We had a great week on Kaua'i, and much of that was due to having a strong "home base" at Joseph's. Easy access onto Rte. 56, beaches south, east, and west, good restaurants in Kapa'a, a fully-stocked Safeway roughly half a mile up the road, great coffee, salads and shave ice at Coconut Marketplace which is a three minute walk away.
We didn't have any need to contact Joseph during our stay, because we easily found what we needed in the apartment. The AC was nice to have, even in March. Kitchen accoutrements were typical for an AirBnB; again, Safeway is just up the road.
All-in-all, we'll certainly consider returning.
