Easily the best place I've stayed with my children. There is a nice selection of toys and books with a space in the lounge room to play. It's perfectly set up for children if the weather turns wet.
St. Kilda Adventure Playground is within the walking distance of a three year old. Public transport is close by, with three tram stops only a stones throw away. There is nothing that isn't a 10 minute walk or tram ride from the apartment.
It's also very quite. There is strange absent of road noise. Normally my youngest would be yelling 'tram! tram!' and running to the nearest window every time he heard a ding ding ding. Mostly places I've stay in around Melbourne are not this well sound proof. Maybe it's age of the building, which is really lovely as well.
Adam's place is clean, quiet, in an awesome location and is absolutely perfect for families. I would happy stay here again and again and again.
