## Property Overview

TIMELESS TREE-LINE MAISONETTE w/LOBBY HEIGHT CEILINGS, HUGE ROOMS, BIG WINDOWS & WASHER/DRYER
UPGRADED DOUBLE-CORNER CLASSIC IN COVETED FULL-SERVICE ADDRESS w/STUNNING ROOF DECK & STELLAR GYM
ROOM TO GROW LAYOUT (see alt plan) - COOK'S KITCHEN - FULL DINING ROOM - MARBLE BATHS - SUPREME CLOSETS
There are some homes that check off all the boxes: A location near Riverside Park; a meaningful architectural history; a classic yet flexible layout (see alternate plan) that works well for today's big life; large rooms; attractive light from three exposures; a peaceful/quiet vibe; leafy tree-line views; a sizable foyer/gallery; a big windowed kitchen with ample marble counters, custom cabinets and top-notch appliance suite; a large corner primary bedroom; a big corner guest bedroom, a bonus guest room/den, an elegant and flexible dining room (bonus bedroom, anyone?); two full marble, windowed baths; a washer/dryer; ample designer closets; office space; pet friendly; primo building roofdeck; impressive building gym; building lounge space; live-in super; wonderful staff; top-shelf location; lobby height ceilings; hardwood floors; and a comfy, easy-to-live soul that stays relevant forever. All of these seem to be the very attributes that take the cake on the prime Upper Westside. Well, if you're keeping score and checking boxes, then your smile should be pretty big about now.
Soulful, timeless, and easy-to-love, this double-corner, triple exposure home is a winsome standout for all the best reasons. The winsome vibe and grand scale come together with a plan and flow that really work. Ceilings soar extra-high above you, solid hardwood planks are underfoot, and all around you is classic, vibrant beauty.  Form, function, and flow reign supreme in every room. From the well-scaled living room (big enough for a living/dining if you need to flex an extra bedroom out of current dining room) to both comfortable main bedrooms (both with dual exposures via big cross-breeze windows); from the attractive and practical kitchen to the impressive guest/den space (with washer/dryer); and from the classic windowed baths to all of the custom closets, this feel-good find is a residential stand-out.
Sweetly positioned in its well-served, seasoned Pre-War building, this treasured address is where Rachmaninoff lived and composed his most famous works, and where Barbara Streisand filmed her 1996 comedy “The Mirror Has Two Faces."  The building’s amenities include a brand new river-view roof deck, a well-appointed new gym, building lounge space, and storage/bike/laundry rooms. This well-run cooperative has been described by The New York Times as “A Calm Oasis Near the Buzz of Broadway” – a deserving credit courtesy of its prime location. Every area cultural, shopping, and dining destination -- as well as Riverside and Central Park (and a plethora of easy transportation options) -- are at your doorstep.
Your marvelous maisonette is ready to welcome you home.
(NOTE: Buyer pays 2% flip tax. There is an assessment of $269.12 per month for basement repair & renovation through SEP 2027.)

### How this price compares

- **Last sold price**: $2,150,000
- **Median sold price**: $2,250,000
- **Difference**: -$100,000 (-4.4%)
- **Comparable sales**: 160

- **Middle half of those sales**: $1,709,767 – $2,950,000

Based on co-op three-bedroom sales in Upper West Side.

Square footage is recorded for only 49 of these 160 sales (31%), so no price per square foot is shown for this group. Co-op sales rarely carry a floor area, and a figure drawn from a handful of them would not describe the rest.

This building has not had enough comparable sales of its own in the period to support a median, so the benchmark is drawn from Upper West Side instead.

### How these sales were negotiated

- **Sale-to-list price**: 96.7% (147 sales)
- **Sold below asking**: 65% (147 sales)
- **Typical time to find a buyer**: 74 days (152 sales)
- **Typical time to close**: 91 days (154 sales)

Based on co-op three-bedroom sales in Upper West Side with the required listing and closing data. Sample sizes vary by metric.

These are two separate periods measured on different clocks — time to find a buyer, and time from agreed deal to closing. They are medians of different sets of sales and do not add together into a single "days on market" figure.

Sales data through August 2026.

Sale prices are the consideration recorded with the City in ACRIS, and each sale is dated by the day the City recorded it. A closing date reported to the MLS typically falls one to two weeks earlier. Recorded sales describe what has already happened and are not an appraisal, a valuation, or an estimate of what this home will sell for.
