Visiting in February (the "off season" for travel/tourism) I paid only $125 per night at Little Charlie. The accommodations were perfect. The room was modern; the twin bed was incredibly comfortable; and the shower was hot. Noise level was fine, though I brought my own earplugs.
The hotel was pretty high tech. Before arrival, expect an email with an invite to download an app and start the check-in process. Note that the front desk is NOT staffed overnight, and the front door locks for security -- so if you plan to arrive after 8-9 PM, you'll need to use the smartphone app to pre-check in and obtain the access code required to open the front door. The app can also be used as your room key, or you can get a standard key card.
In your room, the curtains are operated by a remote, as is the AC/heater. There's a mini fridge, with free Fiji water, which is a nice touch. Included breakfast of croissants, muffins, pastries, coffee, and orange juice or lemonade was a good way to start the day!
The hotel is located a convenient 9-minute walk from Grand Central, which can get can get you just about anywhere in the city via subway.
If you're like me and plan to attend Broadway shows every evening, the major theaters are only an 18-30 minute walk away, depending on which one you're going to. Anxious/uninitiated NYC tourists could find the long walk back in the dark intimidating, after daytime crowds are gone, but keep your wits about you, and you'll be fine.
I recommend this stay!
