If in the future I am looking for somewhere in Sydney, I would try this first.
It's location about 7 minutes to the station means that you're in the city in 15 minutes - really handy.
Marrickville has a great atmosphere and terrific food.
Being a snorer, I used the airbed in the second room - quite comfortable even for a fussy sleeper!
Really solidly built block - no noise from other residents - ear-plugs may be handy if you're a light sleeper for the road noise. (But then, I come from a rural area, so any noise is difficult for me!)
