Sydney Hotel Recommendation

Can anyone recommend a good central hotel in Sydney? I'm going to Oz in a few weeks and am staying in Sydney for 2 nights. I've been looking at the Holiday Inn Old Sydney which seems quite reasonable for its location. Anyone know what it's like or any other hotels in the area?

If you use some of the review sites mentioned in this thread it might help.

I personally like staying in Darling Harbour near Paddy's Market & China Town... The monorail is right nearby, so you have easy access to Darling Harbour, Centrepoint Tower, Queen Victoria Building, etc, etc... and for a couple of $ for a daily ticket, you can hop-on and off as many times as you like. I highly recommend this location if you're staying in Sydney!

I try to stay in the Clarion Suites whenever I'm in Sydney. It has lovely apartment like rooms. If that's booked up, then my next hotel is [broken link removed]. To book these hotels, wotif is a GREAT site.
