My parents have just returned home after a holiday in Australia. As they were going to be traveling around Australia and wanted to base their travels from Melbourne, they came across a small rental company called Australian Home Away (www.australianhomeaway.com).
Their hosts Bob, Sandra & Susan did everything possible to assist in their requirements and provided good quality accommodation in various parts of Melbourne.
So, if any of you or your friends get stuck with finding a place to stay, give them a call.
