Manhattan does not typically spring to mind as a place to savor sunsets. California beaches perhaps. Or Key West where nightly sunset parties are thrown.

But at the Greenwich in Tribeca, the little boutique hotel opened in 2008 by Robert DeNiro, sunsets are a star attraction. Many of the 88 rooms and suites overlook the Hudson River. The best view, of course, is the two-bedroom penthouse suite with a floor-to-ceiling glass dining room, but even normal courtyard rooms (401 and 402, for example) have outdoor patios and curved art deco glass for drinking in one of nature’s most spectacular performances.

The low-key show is the perfect metaphor for this quiet Tribeca hotel that Donald Glover, from the NBC comedy “Community,” chooses whenever “I’m not in the mood to party and want to be alone.” It’s the kind of place where stars like Jennifer Aniston, Jude Law and Rhianna go for contemplation, for taking a deep breath after walking the Big Apple’s high-energy streets.

DeNiro, known for his obsessive attention to detail in movie roles (he gained 30 pounds to play boxer Jake LaMotta, for example, and paid $5000 to have his teeth ground down for his role as a convicted rapist in Cape Fear) spent six years perfecting the Greenwich. Built on the site of a former parking garage, DeNiro’s masterpiece makes great use of hand-cut terracotta tiles from Italy, hundreds of thousands of specially-commissioned bricks and massive oak beams from defunct factories.

No two rooms of this boutique jewel are like. Each room is individually decorated with such touches as antique silk rugs, Siberian oak floors (the suites have American pine) and bathrooms with elaborate Moroccan tile mosaics.

The Shibui spa, located in the basement, was brought over piece by piece from Japan. The 18th century bamboo and wooden structure, constructed without benefit of nails or screws, was reassembled by a staff of 13 artisan craftsmen, flown 16,000 miles from Japan. The spa’s zen-like pool is lit by lanterns and spa therapists use jasmine, freshly-pounded for each treatment.

Russell Brand and Katy Perry, two months after their elaborate Indian wedding, enjoyed the attentive service at the Greenwich, far from paparazzi eyes. Cameras are forbidden and the entire staff (from maids to valets) undergo intensive butler training.

All extras are free from the goodies in the mini-bar to the wifi to the rollaway beds which like the normal beds feature high-end Swedish Dux mattresses. The New York Times is delivered to each doorstep, but if guests prefer say Le Monde or the Sydney Morning Herald, that’s but a phone call to the concierge away.

This stunning hotel is located on Robert DeNiro’s monopoly piece of Manhattan, next to his Tribeca Movie Studio and his Italian bistro, Locanda Verde. To find out more about Robert DeNiro’s “piece of the rock,” click here.
