We had a trip with another family (total 4 adults and 4 children ages 10-13). Jessie's place is perfect for all of us. The host is responseful to any questions that we have.
The minor gripe is the location to the city center (or CBD), as it takes about 30 minutes by bus to get there, plus the 10 minutes walking to the bus stop of the main bus lines. There is another bus stop that is two houses away that will take you to Bondi Junction that will take you about 25 minutes. The nearest grocery (Coles) is 15-20 minutes on foot.
Overall, this is just perfect for 8 of us. The house is stylish and homey for all of us. Our families had a great time in Sydney.
