All New York City loft lovers should check out this apartment for sale at 11 West 20th Street, a prewar Flatiron condo building. It’s a big space with two bedrooms, a den, home office, and three full bathrooms, plus plenty of those lofty prewar details. High ceilings and big windows, of course, are a given, and then there’s tons of exposed brick to go around. You’ll find it in most every room, some natural and some of it whitewashed. Now on the market, this apartment is asking $3.85 million.
