Fantastic location in Kirribilli! Easy walk from either the Milson train stop (10 minutes, ~5 blocks, mostly downhill) or the Kirribilli ferry stop(5 minutes, ~3 blocks, gentle uphill plus steps from the ferry terminal).
The space is delightful, a large efficiency apartment with everything but a stove. Very airy, with views looking out onto the beautiful courtyard they have built. I went to sleep to the gentle sounds of the courtyard fountain.
Cynthia and Mic were wonderful hosts, providing information on how to get around, local spots to eat, and suggestions for places to visit.
