Tracey and Michael have a modestly sized flat in a nice location (very near the harbor) that will comfortably accommodate up to 4. The apartment is very clean and quiet, and boasts amenities such as a ground floor gym, sauna(!) and whirl-pool.
Our hosts were superfantastic and provided us suggestions for sites, eateries and so on to make our visit to Sydney memorable. Whether you are a walker or prefer public transportation, the apartment is conveniently located to downtown and all the sites you "must" see.
Definitely a great value.
