Hotel Brasserie Au Violon. The former residents here—priests and prisoners—never had it so good. Housed in a 12th-century building that served as a cloister and then a prison, the hotel now captivates its clientele with subdued elegance, a peaceful location, and a terrific restaurant. There are some reminders of the building's austere past—guest rooms overlooking the courtyard still conform to cell-block arrangements, with uniformly tight square footage. Guest rooms facing the town offer more space at a slightly higher rate. The brasserie, with its mirrored bar and iron-legged tables, serves French classics.
