We had an all-too-brief 2 night stay at Eagle's Nest, and loved every moment of it. First of all, the views are as incredible as pictured, if not more so. The lack of greenery during winter didn't affect them, if anything our view was more unimpeded by the bare trees. The house is obviously built to take best advantage, with a full porch along the mountain-side of the house, and every room containing oversized windows. It makes a dramatic way to wake up, I can say.
Beyond the views, the house itself is very private and has a ton of character. There is lots of rustic woodworking detail and several rooms have laddered loft spaces. Whether you need that additional space or not, it gives the whole house a lot of visual interest.
We also loved the town of Woodstock, no more than 5-10 minutes away, which had a lot of quaint stores including the obvious festival tie-ins. Touristy, yes, but still interesting to explore. The owner makes several restaurant recommendations, and the few we tried were well worth it. The Oriole makes a great breakfast.
