303 East 77th Street | Upper East Side

Isis is a new construction condominium with a prime Upper East Side location at 303 East 77th Street. There's more to Isis than a plum spot on the Upper East Sde, though: the condominiums for sale at Isis offer luxurious amenities and one of the rarest luxuries in Manhattan real estate -- privacy. With spacious condos for sale and just 32 apartments spread over the building's 18 floors, Isis isn't just one of the most family-friendly condominium listings on the Upper East Side. It's one of the most private condo listings in Manhattan, period.

The elegant marble and stone lobby – and 24-hour doorman – set the sophisticated tone at Isis. The amenities at Isis Condominiums are a top-to-bottom affair, though – literally, thanks to a fully landscaped rooftop terrace complete with daybeds, lounge chairs, and grand views of Manhattan’s Upper East Side. Isis is also among the safest condo listings on the Upper East Side, thanks to a fully integrated video intercom security system.

Every condo for sale at Isis features hardwood flooring throughout, high ceilings, and a flood of natural light thanks to oversized Wausau windows. The kitchens at Isis boast Poggenpohl cabinetry and top-of-the-line appliances such as a Subzero refrigerator, Viking range, Asko dishwasher and Marvel wine cooler. High quality white quartz has been used for the kitchen countertops and backsplashes. All condos for sale at Isis feature heated bathroom flooring and steam showers, and many of the apartments for sale also include private terraces or balconies.

Manhattan’s chic Upper East Side is home to some of the finest private and public schools Manhattan has to offer, as well as many of New York City’s best restaurants. At 303 East 77th, Isis is at the very heart of it, and just a short walk from such iconic Upper East Side destinations such as Central Park, The Whitney Museum and The Metropolitan Museum of Art . It's also just steps to the subway from Isis, and the nearby 6 train provides quick and easy service to other New York City destinations.
