Yes, you should absolutely stay here.
The NoMad was everything I had hoped for and more. I spent a few days doing research on where to stay as I wanted comfort, cleanliness and a peaceful night sleep and I am so glad that I stayed here. The staff was friendly, no attitude at all - and very eager to help whenever I needed assistance (wake up calls, luggage storage, cabs) no problem.
My room was so clean and comfortable! Now that I am home, I often find myself missing my bed at the NoMad. I slept so good and the hotel was very quiet. The room was also well equipped with all the little luxuries you could hope for. They offer a fully stocked mini bar but I still suggest grabbing anything at a local Duane Reade to save some cash. Make use of the bathtub after a long day of walking around the city - you'll be glad you did. 
Finally, the overall decor of the hotel is truly represented in the photos posted by the hotel as well as guests. Charmingly Parisian. I felt like I was in my own apartment, not a typical hotel room at all.
