Ali is a great host. I mistakenly booked an early start date which i had to change 1 week prior to our check-in date. Ali quickly accepted my change request. This place is much nearer to train station than shown by Google maps (there is a walk-way which Google does not take into consideration). If you're new to Sydney, you can buy free Opal card (pay for top up) on your way to train station at a newsagency.
I would recommend Ali's place.
