I stayed with here with my wife over Christmas. The resort was exactly what we were looking for in that it was secluded, private and quiet. You really had that secluded island feeling in all the rooms, even though there were others around. It is on a remote island, so not all the things from a mainland hotel, but we liked that. The best was you could bike/walk about 30 minutes to the other side of the island to really a very private beach. The wifi was good and the breakfast was awesome. The service was really good on the island. The process of getting from the airport and across on the boat could maybe be a little more relaxing, but that is just being picky. It was a little difficult to get on and off as the private boat transfers and taxis provided by the hotel were a bit expensive, so just plan on staying at Naka while you are there.
I would highly recommend if you are looking for a private island experience, but want good food, nice staff and great rooms.
