The Hunter Resort is good, but it is a good modern "motel style" with high timber ceilings and lots of light - vines grow right up to the back door - ever so peaceful in the morning. Also has an excellent restaurant and winery - one of the first to have accomodation in the Hunter Valley. It is right in the middle of a vineyard at the quiet end of the valley towards the New England Highway. Had excellent service when I was there, but I would think most places are good. Not sure if you are looking for something like this though?
For something out of the ordinary/quirky, also check out the Wollombi pub on your way back to Sydney - typical Aussie pub, but they also sell a viscious port called "Jungle Jim's Jungle Juice" - goodness knows where it comes from. The village is a bit of a detour, but the drive is nice, through some big forests and away from the freeway.
