My wife and I stay almost exclusively at B & B's when we travel and this one ranks up there with the best we've stayed in.
Steve and Patti (proprieters) are two of the most friendly people you will ever meet. Starting with Steve's "sit down" to explain Cooperstown's attractions, it's History, and where the best places are to eat (both have extensive experience in the restaurant industry), Steve and Patti go out of there way to make you feel as comfortable and welcome as possible. The home itself is as clean as can be and is tastefully decorated.
Oh, I almost forgot, Steve's breakfast creations are fabulous !
My wife and I strongly recommend the Rose and Thistle if you are making a visit to Cooperstown. We left knowing that we not only had a great time but also made some good friends.
