We stayed one night during the week at the Hearld Square Hotel which is a very clean albeit old, small hotel located on 31st Street between 5th Ave & B'way. The rooms are tiny but we didn't care. I know their rates fluctuate depending on the time of the year and the day of the week and when you book it but we got a room for under $150 including tax for a Tuesday night. I would definitely stay there again if the price was right. http://heraldsquarehotel.com/ Good luck and see you there.
