I highly recommend staying with Lorraine, and would personally do so again in a heartbeat! Her home is very comfortable, clean and relaxing, and you get to enjoy the company of Lorraine and her two entertaining yet very well-behaved Labrador retrievers!
Lorraine was quite welcoming and went out of her way to ensure I had a pleasant stay... she even picked me up from a farther train station after missing my connection. She was also a wealth of local knowledge - she recommended places to see while in Melbourne, good restaurants in the area, how to get about town without getting completely lost, and really anything I needed to know to make the most of my time in Melbourne. It was all very much appreciated.
The house itself is close to tram lines, and in a safe, and quiet neighbourhood, so if you're looking to be close to the city, but not endure the noise and busyness of it, this is the place for you.
Thanks again Lorraine, Abbey and Tilley!
