This was the perfect place for me to enjoy Sydney. There's a bus stop at the stop light at there foot of the hill. Four stops to the Rose Bay Wharf and Ferry one way (and then to Circular Quay), 1-1/2 dozen stops to Town Hall station the other. The buses go to Watkins Bay, and the ride is like sight-seeing. Don't miss Watkins Bay.
The retail district of Rose Bay has most everything you need. I ate at the Italian Restaurant on my last night, and enjoyed myself a lot.
My hosts treated me like family. The home and outbuildings are beautiful. I couldn't have asked for more.
