Sleek, spacey, modern, and new
Stayed here one Saturday night with two friends, in a suite room with two beds and a pullout. The hotel is beautiful, with custom art in the lobby and serpentine couches that would fit in on a space station. Lobby staff was helpful with directions and recommendations for restaurants and walking routes.
The room was grand, with deeply frosted glass walls and doors separating the bathroom and small kitchenette. The shower stall was huge- easily could have fit four people, with a ceiling mounted rain showerhead and handheld jet. Many room functions were controllable from the TV remote, such as lights, temperature, wake up calls, etc. I slept on the pullout sofa and it was more comfortable than many hotel beds I've slept in over the years. 
We visited the roof top bar for a cocktail at the end of the evening. Though you don't get a great city view, it's a pretty sight across the river to the Statue of Liberty and opposite shore. You could also see the World Trade Center tower going up behind the building. It's drinks only, and prices remind you that yes, you are in New York City. 
It's a couple of blocks walk to the subway, but easy on a day with good weather, and cabs were plentiful. It's a quiet section of the city on weekends, for now, as construction continues at the World Trade Center site, but this will be a great place to stay if you're visiting the memorial.
