Description

New at the Ansonia Clock Factory! Welcome to 438 12th Street #6D - a 1,440 sf two bedroom, two bath condominium (originally designed as a three bedroom - see both floorplans) which has the layout that makes you understand why people fall in love with loft-style living and never look back. Enter to east-facing factory windows in a landmarked conversion. Morning light is nearly ethereal and happens again in the afternoon when the setting sunlight bounces off the sister building across the courtyard. Giant Windows, high ceilings, hardwood floors, an open concept kitchen, washer/dryer, and two classically tiled full baths. The flow is easy and the closets are bountiful. This building is well-loved and well-run - a full-time doorman, live-in super, and a beautifully landscaped courtyard shared among residents. The kind of outdoor space that makes the whole building feel like a community. And then there's the dream setting. Spectacular restaurants frame both ends of the building - the kind of lineup that makes you feel like you won something the first time you realize it's all right there. Add Prospect Park, seamless transit, and the gourmet markets and boutiques that have made this stretch of the South Slope one of Brooklyn's most quietly coveted addresses. Blink and you'll miss it!
