I come to Sydney for business four times a year always staying somewhere between the airport and UNSW. Ronit's place might be the nicest place I've stayed. Behind a locked gate on a quiet street, it is clean, spacious and efficient. Bathroom is large and hot water plentiful.
At the end of the street are bus stops going both north and south on a main route. North, you can be in the City in 17 minutes, south to La Perouse in 10. There is a shopping area on Anzac Parade within a 15 minute walk with supermarket, excellent fish market, several restaurants and a bottle shop. Westfield Mall is south one kilometer and has three floors of shops. Snape park is nearby, one circuit is almost exactly one kilometer. Nice running track.
And Ronit is super friendly.
