Can anyone point me in the direction of a website that has reviews of accommodation by area or by searching for the name of a place?

I am heading to Ballarat in a couple of months for my grandmothers 70th birthday/family reunion, and am trying to decide between a couple of places to stay. a review might help to make up my wife's mind for me

If anybody has any recommendations for accommodation for a family of 5, that would be helpful too.
