Stayed at the KI Coastal Villas for a few days as a base while I went driving around the island. I was in one of the air conditioned family units, which had a kitchenette with a stove and a full sized fridge. This was handy as there aren't a lot of places that are open after 5.00 in American River most nights, and driving to either Kingscote or Penneshaw for dinner runs the risk of roadkill, so being able to cook for myself was useful. If you're happy to have an early dinner though, there's plenty of options within a 30 minute drive if you don't want to eat at the three or four places in American River.
The cabin was small but comfortable. There were two bedrooms, one with a king size bed that took up a lot of the room, and another with a bunk bed. There aren't much in the way of cupboards, but the shelves are enough to store a few days worth of clothes. Bring some coathangers if you want to hang anything up.
The main living area had a small round table for four and a couch with a TV above the fridge. There's a small deck with a small table and a couple of chairs if you want to take in the sounds of wildlife.
The beach is at the end of the driveway, with a playground, tennis and basketball court, and a 'take-a-book, leave-a-book' library attached to the shelter shed nearby. The boatramp is a five minute walk away with a cafe open 9-5 (try the eggs benny!).
Great spot to unwind at and just relax.
