We loved the location in St Kilda, easy walking to shopping and restaurants as well as the beach. Tram station is very close by that will take you downtown. We had a car rental and parking on the street was a hit or miss, not easy to find a spot on the same street and had to park somewhere else in the neighborhood in a couple occasions.
The flat was nice and clean with most of what you'll need. I would stay here again if I was in the area.
