Mark & Lizzie are a brilliant hosts, making sure everything is good and that you're comfortable in the flat, before your stay and during as well. They love to cook (like me) and therefore we had a great time sharing each other's dishes.
The property is within walking distance to the train station and commutable distance from the CBD (around 15 minutes). There are shops and restaurants nearby that Mark & Lizzie are more than happy to point you in the right direction. All in all I have a fantastic stay with them and when I go back to Sydney I will be sure to go visit them.
I wouldn't hesitate to recommend anyone to stay with them whilst you're in Sydney
