As a first-timer & solo traveler to Sydney, the question of how to get to the place is important. I’d suggest to use Ready2go shuttle bus at $34 round trip than catching a train & bus. The shuttle bus is a door-to-door service. If you are traveling with a companion up to four, then you might want to consider Uber for a cheaper cost since everyone can share the cost.
Daniel’s place is less than 10-min walk to U Sydney & less than 15-min walk to the CBD. You will see supermarkets/restaurants for grocery needs like Coles, Target, food court and a variety of restaurants: Vietnamese, Korean, Japanese, Chinese, Western food etc.
