Schlosshotel Münchhausen
This 17th-century castle was converted into a top-class luxury hotel in a manner that retains much of the original charm and decoration without sacrificing modern amenities, including a spa and swimming area. The rooms are spacious and luxurious enough for visiting dignitaries, and most have great views of the surrounding grounds, which make for a lovely stroll. Dining here is also top-notch, with a not-to-miss breakfast buffet and two restaurants, including a well-regarded fine-dining restaurant (dinner only; open Wednesday to Saturday).
