Just stayed at gorgeous convict built and self-contained 4 bedroom Semaphore House at Saltwater River on the Tasman Peninsula. It's about 20 minutes from Port Arthur in a magical setting overlooking the bay. The house has everything you could need with huge kitchen, 4 comfy bedrooms sleeping 8-10, 2 living areas and glorious walled cottage garden where you can sit and watch the kids playing cricket in the field overlooking the bay. There is also another colonial, convict built house available across the road - The Surgeon's cottage. Have a look at the website www.tigerbayretreat.com.au. Highly recommended as a base for exploring the Tasman peninsula with lots of space and charm!
