Description
This is a large and bright two bedroom, two bath home at the full service Diamond House Condominium. The apartment features a spacious layout with North South and East Exposure for good light throughout the day.One enters the home through a convenient foyer complete with comfortable coat closet.
The entry foyer leads to a oversized, open living / dining room. As it is a sunken living room, it offers a higher ceiling height and is visually separated from the dining room. This visual separation is enhanced by the stylish designed custom built in wall unit/media closet that adorns the living room wall. The exquisite, windowed, eat-in kitchen has top of the line appliances including Thermador range and dishwasher as well as Sub-Zero refrigerator and wine cooler.
The well-proportioned bedrooms are split North/South and share no walls with neighbors or each other. Both bathrooms are windowed and boast high quality finishes with a combination of stone, marble and glass tiles. The main bathroom has a deep soaker tub while the ensuite has a large glass fronted rainwater shower. Beautiful, genuine hardwood floors flow throughout the apartment and there is generous closet space, including two walk-in closets, one of which can be used as an office space.The home comes complete with a Bosch washer & dryer in the unit, through wall air conditioning and a large private storage unit.
Diamond House is a mid-sized condominium building conveniently located in the middle of the Upper East side. It is close to great shopping, gourmet retailers, restaurants, schools, and Central Park. But if you need to get away, the subway is half a block away or by car you can be at one of the East River crossings in minutes. The building has many wonderful amenities including a 24 hour doorman, live-in super, sky-lit fitness center, bike room, a landscaped roof-deck and separate washing area for larger items.

About Upper East Side
View All Upper East Side ListingsThe Upper East Side remains the gold standard for classic New York elegance. Known for 'Museum Mile' and its low-traffic, tree-lined streets, the neighborhood offers a refined lifestyle away from the midtown bustle. While famous for its historic cooperatives, the area has seen a recent surge in ultra-luxury new construction condos, particularly along the Second Avenue Subway corridor, making it a top choice for both traditionalists and modern buyers.
