Maria has a great place in the centre of the small town of Dorrigo. All shops are really close by. It is also a great place to stay when visiting Dorrigo NP.
Note however that it can be really cold in winter. Given the age of the house, it will also get quite cold inside. There are some small electrical heaters and there is a unflued gas heater. I would therefore advise to take a CO detector if you plan on using the heater.
I had a great time in Dorrigo!
