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).
