Description

This large two-bedroom, two-bath home in the heart of Carroll Gardens leaves nothing to be desired! In a boutique, 7-unit, modern condo building, the proportions and layout are ideal. Enter into the vestibule, complete with a large coat closet, and turn the corner into the spacious open living area. With plenty of room for living, dining and a home office, the size of this space is noteworthy. A wall of windows and sliding glass doors out to the balcony brings in beautiful light throughout the day and looks over the serene gardens below. The custom kitchen has stainless steel appliances, Caesarstone counters, and an abundance of work and storage space. Separate from the living space, down the hall, are the two generously proportioned bedrooms. Both have large closets complete with the Elfa system, with the master bedroom boasting a windowed, en-suite bath. Both bathrooms have modern fixtures and finishes. Other features of this wonderful home include high ceilings and hardwood floors throughout, great closet space, a new Miele washer/dryer, and central air conditioning. The condo is pet friendly too! Located one block from the F/G trains at Carroll Street, perfectly situated between Court and Smith Streets and all of the amenities each has to offer, and one block from Carroll Park, the location is simply unbeatable.
