"Designed as the National Maritime Union headquarters in 1968 by modernist architect Albert Ledner — who studied under Frank Lloyd Wright — this nautically themed hotel has a boatload of charming details, from porthole windows to sweeping views over Chelsea. But perhaps even more unique is what awaits on the private white-tiled patios overlooking the Hudson River: the elusive metropolitan outdoor shower. Is there anything dreamier on a sticky summer day? There are a lot of things you can do outside in New York City; getting naked in public isn't a commonly accepted one. So, go ahead — this is your prime opportunity to strip in broad daylight in the middle of Manhattan." - Travel + Leisure Editors
