Nice Theater District Spot
My wife and I like to travel into NYC for a Saturday night Broadway show a few times a year and make a weekend of it by spending Saturday night in town. We call it our "Play-Date”.We usually check the Travelzoo website for good deals on the Millennium and Hotel Mela located on the same street. The millennium is particularly handy during the frigid months due it's close proximity to both good restaurants and theaters - they was one instance we walked out the front door and had dinner across the street at Osteria al Doge - went back into the hotel and and through it to W 45th Street and walked less than a block to the show. Staying warm is critical when the wind is blowing down those streets. 
As for the rooms, they are completely clean and comfortable. We like asking for the high floors so we can hear the wind blowing outside, and get a better view of the colorful Times Square scene. BUT, make sure you get the discounted price at Travelzoo.
