We stayed for four nights in Vivien‘s Darlinghurst apartment . The location is pretty good , a lots of cafes (highly recommended is the organic bread cafe 2 houses away) are nearby . The apartment itself is also pretty , but smaller as expected . We were two of us and had problems to find space for suitcases :)
The noise which is mentioned in AirBnB description is also there , but was ok for us (once we used ear plugs)
All in all we had a good stay , for those who aren’t that sensitive for noise or traveling with lighter luggage the place is a perfect . Kings Cross nearby (10min Walk) and you can use Opal to explore Sydney.
