This unique hotel is part of the Castle Cottage – gothic manor located in West Sussex and surrounded by lavish green countryside and forests. The Treehouse is built around chestnut tree, so you’ll have a living tree in your bedroom! The decor of the house flawlessly combines with the forest environment, which you can watch from the swing(!) on your terrace. If you're looking for more fun you can also try guided walks, horse riding, gliding, pilates or...hot balloon flights!
