Prestonfield House is a five-star boutique hotel located in Prestonfield, Edinburgh. It was originally built in 1687 by architect Sir William Bruce, and was once a wealthy rural estate, but in recent decades has come to serve as a hotel. Though it is a small establishment, having only 23 rooms, Prestonfield House is well renowned by critics. Situated on extensive grounds at the foot of Arthur's Seat, Prestonfield House also owns a large roundhouse, which was previously used for keeping horses.
