Apartments with slides are the best. And while the one in this three-bedroom on East 11th Street isn't of the shiny, tubular variety, it's pretty darn cool nonetheless. Digital ad agency guru Joon Yong Park bought the loft in 2011 for $1.925 million, back when newborn baby Dylan had recently entered the picture. Now, after a renovation by James Ramsey of RAAD Studio and Lowline fame, the apartment has three awesome spaces for kids, including a pair of desks under a lofted chalkboard-painted area. Up there, you'll find a li'l fort that's accessible by ladder, plus a slide for wee ones to scoot down when playtime is over. The rest of the apartment is pretty lovely, too, with exposed brick and lots of storage. It just hit the market asking $3,995,000.
