We spent Two nights at Dan & Erin studios and it was ok. Is in princeville, next to Hanaley. It's quite big with a nice lanai , clean and well equipped. You can buy your own food and cook it if you want. There is just one missing amenity ... Hair drier but the rest is very good. They are very responsive and the let us check out a little bit later. In my opinion the north shore is the best part of the island, if you want to hike remember to be equipped and well trained, the trails are not for everybody.
So Kauai is north shore and the studio is a right place to stay.
