Washington Mews might be one of the best blocks not just in Greenwich Village, but in all of New York City. It’s a gated, cobblestone street that’s lined with quaint carriage houses and one of them has just hit the market, asking $30,000 a month. Located at 64 Washington Mews, it’s been totally renovated into a lofty and modern two-bedroom home with three levels connected by an open staircase and lit by skylights.
