You literally cannot get a better location in Sydney! We stayed here for a week and it was the perfect location to explore the city. We were able to walk everywhere. Apartment is in the heart of the city and is very close to everything you need - coffee, restaurants and grocery stores.
Apartment itself is also very nice. Very clean, usable, convenient. Host is amazing and made sure to accommodate our every need, including providing a high chair and a baby cot for our baby which he bought brand new for us! All in all - a great apartment, great host and unbeatable location. Highly recommend!
