Alexandra Champalimaud has brought her refined modern style to Philadelphia with her redesign of the city’s classic Rittenhouse hotel. Shown here, the new Library Bar features a 20-seat bar built around back-lit onyx, as well as herringbone-patterned oak floors, golden leather bar stools, and a seating area with a limestone fireplace and a black glass chandelier. Additionally, a refurbished Mary Cassatt tearoom and redesigned guest rooms—including five Park Suites—were completed late last summer; a spa will debut later this year. 800.635.1042, www.rittenhousehotel.com
