Liam is an excellent host. We stayed for 2 months, and he responded to all of my questions very quickly. The bed is also quite literally the most comfortable bed I've ever slept in. The location is great if you want to spend your days close to St. Kilda beach (it's less than a 10 minute walk) and the public transit in the area is perfect- you do not need a car.
My only constructive feedback that might be helpful for other travellers is that I don't think it's an ideal home for very small children. My kids are ages 7 and 4, and the walls are really thin in between the neighbours. My 4 year old is LOUD, so I felt really bad that the neighbours could hear his every word, and it was a bit stressful constantly trying to quiet him. Also, there's no screens on the windows (which is very typical for heritage homes in the area- I didn't realize as an out-of-town Canadian) so the windows made me a bit nervous with little ones.
Overall though, defiantly a great place to stay! :)
