Riverwalk Court, a new condominium on Roosevelt Island, has a stylish look and elegant apartments for sale that would fit in perfectly across the river on the Upper East Side of Manhattan. That has something to do with an appealing look that comes courtesy of award-winning architectural firm Costas Kondylis and Partners, but it has more to do with Riverwalk's luxurious apartments for sale and vast array of amenities. From its landscaped greenery and lush gardens to eye-opening views of Manhattan's skyline and the East River, Riverwalk offers a notably rich array of aesthetic benefits.
