I've stayed at Sofitel Philadelphia several times a year for the last 10 years, and every visit is perfect. Besides having a very convenient location in Center City, one of the hotel's strongest points is their service. The staff are friendly, helpful and welcoming. Long-time staff remember long-time guests. Women traveling alone always feel safe. And if that isn't enough, Sofitel is one of the very few hotels that serves loose-leaf tea! Coffee drinkers will appreciate the coffee, too.
