I stayed 9 nights at Brett & Lucy's super apartment. The accommodation is accurately described and would suit a couple as well as singles. The kitchen has what you need for a short stay, the showers room is light and airy and the living space well designed if a bit austere, especially on a cold Winter night. The heater was good though.
For those unfamiliar with Sydney, Kirribilli and Milsons Point are incredibly convenient for the North Shore or Central Sydney and this suited me perfectly. I used the train to get about and the station is really 2 minutes away. I also got into swimming at the North Sydney pool and enjoyed some great walks around the area.
As others have commented, there is a trade off for the amazing location and proximity to transport and other amenities which is that the road outside is used by buses, delivery trucks and other early risers so the noise can start as early as 5am. If you sleep deeply or are used to traffic noise being close then no worries but otherwise be prepared to use ear plugs and enjoy getting the day underway early so you make the most of it.
I'd say ideal for business travelers and busy tourist couples wanting to be close to everything.
Thanks to Brett & Lucy for sharing your place.
