Uncomfortable & "dark"
I've stayed at this hotel many times in recent years and always found it "adequate" (until most recently) even though several in my group had major problems. 
While the location of the hotel is decent, there are many more modern hotel chains in the same area that may have considerably better facilities. While the Doubletree Worthington is known for very cheap rates I think you get what you pay for.
This hotel can be quite loud, especially on weekends. It is often very crowded on weekends with conference type folks and families. When I was there the indoor pool and sauna was packed with about 40 people at 9 p.m. on a Saturday night and teenagers were loitering in the halls. I moved to a different floor and the noise level went down considerably.
During my most recent stay there was a problem with my room, specifically it was left quite dirty after cleaning. After I contacted the desk the problem was dealt with by basically hiding the initial issue. Yes, the hotel staff was very apologetic after my 2nd call, gave me a new room and offered "add-ons" to make me whole, but all I wanted was a comfortable, clean, quiet room where I could get a good nights sleep.
Although I haven't stayed at other hotels in this immediate area, I'm guessing there are better options and even though they may cost more it is probably worth it.
The hotel has a general run-down, depressing feel to it. When the heater turns on the air in the room immediately smells burnt, beds feel worn out and uncomfortable, etc.
