This large apartment in the red-hot Flatiron District has a big, bright and airy feel that is lacking in many pre-war condominium loft buildings, even ones with more famous addresses. (See Adrian Noriega’s listing for all the photos.) The spacious home office is a nice bonus, as are the three full bathrooms, laundry room, direct elevator access and working fireplace. All that said, there’s more to enjoy without leaving the property: The 2,259-square-foot unit sits high on the seventh floor of the Altair 20, a condo that boasts both a gym and a sprawling shared roof deck. Update: This apartment has gone into contract!
