Better than I expected
Work colleagues were not impressed that I had been booked into Hotel Roosevelt so my expectations were not very high when I arrived. However, I was perfectly pleased with the hotel, service, room and everything else associated with a stay in Manhattan.
The hotel is centrally located and NY is very walkable, so it doesn't take long to get to most of the sights I had time to visit. 
The only criticism I would have is that it would be nicer if the rooms were more sound-proofed. I was on the 10th floor and construction on the street below took place all night, waking me on and off. That said, the second night I turned on the air-conditioning in my room so that the hum of the unit would work as "white noise" all night and it worked perfectly. So while not "solving" the problem, the fan did at least mask it!
