It's reasonably priced, in a great location, you get automatic membership to the NSW club which is attached. Rooms are great space with microwave, fridge, sink, decent bathroom. It's a great all round hotel for those on a budget but still don't want to be too far from anything (it's just round the corner from Martin Place and five mins walk from Darling harbour).

For a place to stay, Shangri-la draws the suited and booted but is also the hangout for beautiful people. The Horizon Club serves canapés in the lounge every evening and there’s wireless broadband throughout.
The Somerset Hotel on Elizabeth Street is a brilliant place to stay. It has amazing views over Hyde Park and the Anzac Memorial. There is very good room service with people coming to clean your apartment everyday when you are out. It is near the centerpoint tower and not far from a good pool called Boy Charlton. It is salt water and suspended on stilts over the actual harbour so you get really good views. There is also a brilliant open air cinema on Lady Mcquaries Point. The screen apparently folds down (we didn't get to go there but i reccommend it anyway.)
There are two really good places to eat. One is called Sushi King - it is on George Street and it does the best sushi in the world. The other is the Lindt Cafe on Martin Place - it is really good and they do this great hot chocolate (you get this jug with hot milk in and a jug with melted chocolate in and you pour them in the mug at the same time the result is an amazing rich lovely cup of hot chocolate).
Of course I also reccommend the Sydney Harbour Bridge and the Opera House (my dad conducts there.)
It's close to the SCG, the beers are reasonably priced and the staff and regulars are friendly. Oh, and you can get a decent meal there too.
