In a beautiful 19th-century building, this hotel feels like a bed-and-breakfast, with elegant yet comfortable decor, quiet floors, and well-appointed guest rooms. An intimate atmosphere and the world-class Senhora do Rosário restaurant are among the draws. When you're not exploring the town, have a swim in the luxurious hilltop pool or stop by the atrium for afternoon tea. The hotel even has a section of the mine, discovered during renovations, that originally was on this site. Ask for a room on the first floor; rooms by the garden can be noisy and lack privacy.
