This is a well-designed and furnished flat with a lot of thoughtful touches. There is a very pleasant balcony space and the aircon and fans are really efficient, so you won't overheat. There's also a delightful coffee shop within 100m!
The only downside was the noise during the day - as well being on the flight path into Sydney, there is a metal shop opposite and a mechanics next door and there are periods where they make a lot of noise. That said, it was always peaceful at night and we had no trouble sleeping, so it would be perfect if you were looking to explore during the day. It's also very close to a station for getting into the centre of Sydney.
