Meriton - WorldTower one is close to Chinatown and Spanish Quarter (well actually Spanish Eighth as it is quite small). Really close to Lightrail that takes you to our house. It is in the same building as the kid's nursery - although Adam will be leaving at the end of January and we might move Emily then too. Pitt Street one is also in a good location - Pitt street has some great shops.

Medina - Harbourside one is close to my office but not surrounded by office blocks too much. Grand Sydney one is also close to Chinatown, etc.

Napoleon - also close to my office and therefore Darling Harbour

Somerset -
great location

Realestate - has adverts for holiday accommodation - not quite fully serviced apartments but much cheaper - good areas to look for (apart from the obvious Sydney in general or Glebe - as we are close to the Uni, you have to be careful about the quality of the apartments) are Pyrmont, Annandale (close to us but it is not so close to the city)
