Make sure you get the view
I stayed here two days ago. Upon check-in, I asked for a room with a view as the person I was traveling with had never been to Philadelphia before. We were put on the 23rd floor and had a view of.....the Aramark building (this is not a room with a view!). The Ben Franklin bridge was in the rear of the view, but this is not the view I had clearly talked to the front desk about. When I went to call downstairs, the phone did not work. So back downstairs I went. I had a different clerk from the front desk this time, and she gave me the view I wanted.
The 2nd room was a little bit smaller, but the view was so much better. The thermostat read 65, but it was by no means 65 in the room or during the night. The toilet kept running after the first flush, and I tried to fix it to no avail, and after jiggling around with everything for about 10 min, it finally stopped running and worked properly.
The beds were comfortable, the bathroom was nice (though the shower was low on hot water late in the night, it wasn't cold, but not hot hot). The safe in the room did not work either.
We parked in the attached parking deck with the hotel. It was $35 plus tax which was $42. I find $7 in tax to be a bit outrageous, and would love to see what were the real charges. However, it does allow you to park there for 24 hours and you can come and go as you please as many times as you want without getting charged again, so we took advantage of that.
I was told by the front desk the day before that I could check out on the television. When I went to do that the next day at around 11:25 it said that option was not available. So I had to go downstairs to check out and they said since it "was so close" to the actual check out time (which is noon), that their system doesn't allow you to check out on the tv at that time. I do not find checking out 30 min ahead of time to be "close" to the checkout time. It wasn't 11:58 or anything.
The staff was very nice and always trying to accomodate. 
The hotel itself is very nice, modern, and located in a great spot on Market Street. We liked that we were within walking distance to all of the historic sites, as well as some of the newer ones. So it has a good central location.
I would recommend staying here, however, I hope that the hotel fixes the minor things that are broken in the hotel.
