On a quiet street within walking distance of the sights sits this unusual hotel, a converted 16th-century convent. The large, suitelike rooms are ideal for honeymooners, families, and small groups of friends; some are on two levels, and many are arranged around a central courtyard. Pale travertine tiles used to refit some bathrooms provide a pleasing, ultramodern contrast to more traditional furnishings. Smaller rooms are more intimate, and some open onto a little shared courtyard. The gracious owners enjoy chatting in the light and airy lounge; breakfast is served in a glassed-in Renaissance loggia or in the central courtyard.
