Antique portrait paintings, uneven floorboards, and afternoon tea add to the charm of this 1787 house-turned boutique hotel tucked behind leafy Washington Square, three blocks southwest of Independence Hall and the Liberty Bell. With just 16 rooms, the Morris House gives off more of a genteel bed-and-breakfast vibe than a busy hotel one—and it revels in its National Historic Landmark Colonial heritage.  Even the smallest, "luxury" rooms and mini suites in the main house boast original 18th-century hardwood floors, period nightstands, Victorian writing desks, decorative fireplaces, and, er, ye olde flatscreen televisions (discreetly hidden inside armoires). 

The larger Extended and Presidential suites in the carriage house across the garden are a bit more modern in style, but just as homey. 

For absolute quiet, request a room overlooking the formal gardens in the courtyard, where M Restaurant serves contemporary American cuisine in fine weather (and hotel guests get a 10 percent discount).
