Society Hill is Old City’s neighbor to the south. It offers close proximity to the main historic attractions, but in a quieter, more residential setting. The waterfront Hyatt Regency at Penn’s Landing [1] and the Sheraton Society Hill are both fully equipped chain hotels in excellent locations.
Several unique bed-and-breakfasts provide nearby alternatives at lower prices.
