Cliveden House

"Cliveden's outdoor pool is pretty darned special," says Juliet. "Not just because you're hidden away amid glorious rolling National Trust scenery but because you'll also be splashing about where John Profumo first laid eyes on Christine Keeler". If you book Spring Cottage, sold as a secluded luxury suite in the grounds of this stately home and hotel, you can also take a dip in the Thames.
