My mum and I had a lovely two nights staying on Evelyn and Richard's farm. After two nights of camping, we greatly enjoyed walking around the property, saying hello to the goats and the dogs, and spending our evenings defeating each other at Scrabble.
The Tin Shack was very well equipped, with two ACs, a fan, and a heater for the winter months. The kitchen was great for making dinner both nights, and we also made use of the DVD player one night! There's an excellent selection of books and recipe books around to read, too.
Evelyn was a great host; we checked ourselves in but she was available if we needed anything. One thing to note is that there is only mobile reception for Telstra, which we didn't have, but being only 20 mins away from Bridgetown, this wasn't an issue.
We would highly recommend the Tin Shack! I can imagine it would be beautiful in winter, too.
