Bristling with turrets as a real castle should, this accommodation enjoys an unforgettable location, with huge windows framing green fields sloping down to the water. The attractive interior has 20th-century art instead of stags' heads. Bedrooms are all different, with lots of space and character. It's got lively, genuinely friendly owners, and kids will have a ball running around the grounds.
Rooms are £30 more expensive if you only stay one night. There are also various self-catering cottages available (£495 to £890 per week).
