Wonderful hotel in Center City Philadelphia
I stayed in Le Meridien Philadelphia in May 2012. The hotel has a lovely lobby and check-in area, and the decor of my room on the 5th floor was quite nice (as was the view). I was able to check into my room early and was allowed late check out on Sunday. Every employee I encountered was friendly and helpful. The breakfast/restaurant space is well done though the food is not very good - even by hotel food standards.
The Center CIty location is convenient for exploring the city; however, during the week, the federal and state buildings around the hotel attract a less than ideal crowd.
