Godolphin, Godolphin Cross, Cornwall. Sleeps 12
Stay in your very own Downton Abbey with one of these stately holiday homes, run by the National Trust...
Tucked away on a woodland hillside in west Cornwall, the ancient house of Godolphin sleeps 12 and lies like a sleeping giant hidden among trees and gardens. Built over a long period, mostly between the 15th and 17th centuries, Godolphin is crammed with antique charm.
On the first floor an elegant saloon runs across the front of the house with large windows overlooking the woods and hills. Of the five bedrooms, one has a beautiful Venetian glass chandelier and another contains an important historical wall painting.
The house also has a spacious country-style kitchen with an Aga, perfect for cooking for a crowd of friends or family - and with country walks in the beautiful gardens immediately outside; it'll be easy to work them off. It is only a short drive to lovely sandy beaches on both the north and south Cornish coasts, so makes a fabulous base for a great seaside holiday.
