The O Retreat was absolutely lovely and Nickie was a great hostess! I was there with family, so we weren't necessarily "serene" but we had the most amazing time nonetheless. Beautiful house and surroundings perfect for relaxing. We spent a lot of time watching a family of wallabies under the house, playing games, cooking, and driving out to explore Tasmania. Just one thing...make sure you have a 4wd car to get up the driveway!
