Had a great stay in Lavender Bay in Karen's place. The studio flat has everything you need, a kitchen with all the appliances you need, bed and lovely bathroom.
The location was unbeatable with views of Sydney Harbour Bridge at the end of the road, lovely leafy parks nearby and the water's edge only a couple of minutes walk away.
North Sydney, Milsons Point and Kirribilli Stations are only a short walk away and there are plenty of food shops and restaurants close by. I will definately stay next time I'm in Sydney.
Just a note for people with really heavy luggage or mobility issues: there are some steep steps on the outside of the building leading to the flat so keep that in mind. These shouldn't be an issue if you are fit and healthy!
