A 14th-century hotel in the Cotswold countryside, Calcot Manor is 'just what you'd expect from a luxury country house hotel', says Katie. 'But the spa is the real gem. It has a heated outdoor spa pool next to a roaring log fire to keep you toasty on even the coldest days and treatments are excellent'.
