Clean, quiet and comfortable.
My husband and I traveled to PA from 7/14/12 - 7/15/12 with our seven year old daughter. I booked this hotel through Priceline. I bid $90 and got the room with taxes for $111. Check in was pretty easy. I called on our way from NYC to Philly and asked if our room was ready and if they could please call us when it was. They advised that they would. When we got to the hotel they still had not called but I decided to see if they could get us into a room anyway at the check in desk. They gave us a room without a problem. A few hours later we received a call that our room was ready, lol. Obviously, I would advise going straight to the desk if getting into your room early is a priority.
Another issue with this hotel is the EXTORTIONATE parking rate. They should really be ashamed. $46.50 a day? That is craziness. There is a link on the Philadelphia FAQ section of tripadvisor that I used to find a close lot that we paid $43 for from Saturday morning until Sunday night. It is called Parkway and it was located on 12th between Samsom and Walnut. It was very close. We could see it from the hotel.
Other than that I have no real complaints. The room was clean and quiet. The air conditioning worked well. The bed was large and comfortable. The bathroom was modern with granite countertops and plenty of clean towels. The pool was a real selling point for me. It is indoor and was open until 11 pm. There were plenty of kids there and it was a nice way for us to unwind after a long day of sightseeing. 
The Reading Terminal Market is AMAZING! There are many different types of food for all different palates. There was also a Hard Rock Cafe, a Melting Pot and a more upscale Italian restaurant right across the street.
The hotel was walking distance to all the historical landmarks as well. Overall it was a good value and I recommend it.
