Sydney Apartment/cottage/house etc

Hi,

Going to Sydney for a week in November, looking for a self-catering place, 2
bedrooms, for 3 people, prefer an apartment or cottage/house, whatever I can
find, don't mind where in Sydney it is so long as its close to public
transport, so it can be out in the suburbs.

Does anyone know of any reasonably priced apartments, looking at under $200
per night?

Have looked at all the usual websites, take-a-break, stayz, rent-a-home and
searched on google but going insane looking at it all.

Thanks for any advice.

cheers


Linda
