Macdonald Houstoun House, Edinburgh

Walking through 22 acres of quiet woodland, mature trees give way to the soaring whitewashed front of Macdonald Houstoun House, a historic 16th century tower house made to transport you far from city life. Inside it's all fresh and modern – jump into the cool waters of the 18m pool and clear your mind of the day's baggage, or open the doors to the warming cocoons of the relaxing sauna and steam rooms. Dry yourself off and float towards the treatment rooms to experience Decleor's Aroma massages and facials, and if you're feeling energetic, make like the Tudors centuries ago and pick up your racket and head to the tennis court, concealed in a charming walled garden.
