A solid choice
I've stayed here a couple of times. This property is a renovated hotel adjacent to the historic part of Philadelphia, so if you want to see Independence Hall, the Liberty Bell etc you're all set. The interior is all new, modern. Service was very nice generally (athough the bell staff get busy with cars, so I had to go flag my own cab from across the street). The "waterfront" is a block away, but IHMO its not very nice. I did go running "along the river", which means past warehouses etc; little foot traffic. The hotel has a decent fitness center. One night I had to book the "club" rate, which does offer free internet and access to the lounge--overall a pretty good value if you have breakfast there. While you can walk around the old town area, its a long walk or cab ride to the city center or the arts area. 
Overall, this is a solid hotel for both leisure and business. I'd stay here again.
