We stayed at The Rittenhouse when travelling to Philadelphia to see the Barnes. We were upgraded to a suite [thru Amex Fine Hotels program]. Rooms were spacious and light, but in need of renovation. Bathrooms especially need to be redone. It is possible that some rooms were renovated recently and perhaps we should have asked for one. The hallway outside our room needed vacuuming for the 24 hours we were there. Staff was very pleasant but impersonal.
I would definitely recommend if the hotel is renovated.
