Sun pours into this serene apartment facing south over the Upper East Side Historic District, with treetop and townhouse views below and expansive skies above. Meticulously designed by the acclaimed Argentinian architect Alejandro Lacreu, the entire apartment has been renovated to the highest standard, with elegance and efficiency in mind. Only on a yacht does one find such a visually pleasing and ingenious use of space. Bespoke cabinetry in the living room includes a lined silver storage drawer, deep file drawers, pull-out electronic component shelves, a wine and liquor cabinet, china and glassware storage and library shelving. Custom closets throughout the apartment will indulge your passion for fashion and eliminate clutter from your life. A place for everything and everything in its place - there is even a cabinet for your laptop bag.

Gorgeous maple plank floors have been installed over a layer of sound and waterproofing, and a plywood subfloor. The kitchen includes a Viking range and hood, a Sub-Zero refrigerator and a Miele dishwasher. All new through-wall air conditioners and steam radiators with precision controls are concealed behind unique grille work. New windows, a new 20 circuit breaker panel, and new electrical and Internet wiring mean that you won't have to spend precious time supervising contractors or filling out alteration applications.

In a well-run building sought after for its attentive staff, privacy and security, this is a perfect Pied-a-Terre or primary residence near some of the best museums and restaurants in the world. The building has a fitness room, a garden, private storage bins and a bike room. It is pet friendly, with pets permitted at the discretion of the board. Showings by appointment only
