Expect what you signed up for: a 500 year old, drafty, dark, kinda spooky and ABSOLUTELY FABULOUS Castle. It's everything you want in this kind of stay. Easy directions, good communication, not too far away from town but far enough to know you're way.
A couple of nights were during the very rare snowstorms and cold snap. We lost power, as did the entire road. All the better! We had picked up firewood and had candles. Was it chilly inside? Yep, and we lived like medieval earls for a night.
Do not pass up the opportunity to experience this.
