The SoHo loft of Alicia Keys and former PAPER cover boy Swizz Beatz is up for grabs, and boy, if we had an extra $17,950,000 we'd buy it and move right in with our Furby collection! The couple bought the pad from Lenny Kravitz in 2010 and the near 6,200 square-foot living space features, among other amenities, a floating glass staircase, a crazy outdoor space and, duh, a grand piano. Check out the listing photos and some floor plan porn in the gallery above. [Via TheRealEstalker]
