O.K. Hotel, great location
I went with my daughter on one of her business trips to Philadelphia and we stayed at this hotel from 3/10-3/15/12. Our room on the 5th floor had a lovely view of 4th Street overlooking several historic churchyards. There was some traffic noise, but not enough to disturb us. You can't beat the location for its convenience to Independence National Park, the Betsy Ross House and many restaurants in the vicinity of Market Street. Having said that, I did have a complaint which colors my overall enjoyment of this hotel: our bathroom sink only delivered cold water and the bathroom tub could not be "stoppered" to allow for one to take a bath. I contacted the front desk regarding the sink's water temperature, and they sent a engineer to fix it (which he didn't). In fairness, he left a note of apology, and the sink finally ran warm water on the morning we checked-out on 3/15/12. For our inconvenience, the Manager did "comp" my breakfast one morning. Why not the rest of our stay, however?
Anyway, I came away with a feeling that the hotel's location makes it a draw for many visitors, and that it doesn't have to worry much about negative feedback from guests. Would I stay there again? Perhaps, if nothing else in my price range in the area was available.
