Great Hotel - great location
We have stayed at the Hampton Inn Downtown several times. Rooms are clean and large. Staff is very friendly - Door man makes us smile every time - Valet parking attendants are attentive. We texted our number to them and the car was ready for us by the time we got downstairs. (We were in and out alot) 
Fabulous location for Convention Center, Nationwide Arena, Park Street and the Short North. Convention Center is across street, Nationwide Arena is about 4 blocks away, Park Street is behind the hotel one street. If you turn left out of the hotel towards the Short North there are several restaurants, bars, shops. Streets are always full of people.
Currently the hotel is under construction, but heard no noise from it. 
Second floor has large lounge area where breakfast is served (included). Good selection of items for breakfast and the coffee is great ! (and available all day)
