Light pours in from four exposures, with protected open city views. Located just one block from Riverside Park, the apartment sits in one of the Upper West Side's most charming boutique full-service prewar co-ops. Apartments of this scale, light, layout, and condition rarely become available in this prime Upper West Side location. Fully renovated, the home currently offers four spacious bedrooms plus a staff room or home office and three-and-a-half bathrooms within a classic prewar layout designed for both gracious entertaining and comfortable living. The floor plan features a dramatic entertaining wing and two private bedroom wings, creating a balance of openness and privacy. Nearly 10-foot ceilings, oversized windows, hardwood floors, and elegant moldings enhance the home's classic character. Modern upgrades include multi-zone central air conditioning, a smart home system, built-in audio speakers, a full laundry room, and abundant custom closets. Pocket doors allow spaces to open for entertaining or close for privacy. Entertaining Spaces: The formal living and dining rooms span more than 35 feet, creating a spectacular setting for large-scale entertaining, with a pocket door allowing separation for intimate gatherings. Large windows frame open city views, bringing light to the entertaining rooms and the expansive entry gallery. Beyond the formal spaces, the home opens to a sun-filled den/media room and beautifully renovated kitchen, creating nearly 30 additional feet of gathering space-ideal for everyday living or casual entertaining. Kitchen: The renovated eat-in kitchen is designed for both day-to-day and serious cooking. A center island opens to the den while maintaining subtle separation. Custom cabinetry, stone slab countertops, and thoughtful design details include a butler's pantry, breakfast bar area, and built-in home office workspace. Top-of-the-line stainless steel appliances include a Sub-Zero refrigerator and Miele oven, cooktop, vented hood, and dishwasher. Just off the kitchen is a powder room, a windowed home office (formerly the staff room), and a separate laundry room with full-size Miele washer and dryer. Bedrooms: The private bedroom wings offer comfort and privacy, with four generously proportioned bedrooms featuring oversized windows and excellent closet storage. Two bedrooms enjoy corner exposures, bringing in beautiful natural light and open views. The primary suite is impressively scaled, with a large walk-in closet and a beautifully appointed en-suite bath with a seamless glass shower. It enjoys open city views with a peek of the Hudson River, and a western exposure that provides lovely afternoon light and spectacular sunsets. All full bathrooms feature Duravit sinks and either glass-enclosed showers or deep soaking tubs. Designed in 1918 by architect George F.

Prices are the figures recorded with the City, not asking prices. | Unit | Beds | Sold Price | Sold | Source | | --- | --- | --- | --- | --- | | 7E (Apartment) | 2 | $2,125,000 | April 10, 2026 | City record · MLS | | 3S (Apartment) | 3 | $3,127,500 | June 26, 2025 | City record · MLS | | 10E (Apartment) | 2 | $1,750,000 | July 22, 2024 | City record · MLS | | 8N (Apartment) | 5 | $5,400,000 | August 14, 2023 | City record · MLS | | 2S (Apartment) | 3 | $2,800,000 | December 16, 2021 | City record · MLS | Every row is a recorded transaction, including ancillary spaces such as storage and staff rooms where they were sold separately. Those are excluded from the benchmark below. ### How this price compares - **This home**: $5,650,000 - **Median sold price**: $2,800,000 - **Difference**: +$2,850,000 (+101.8%) - **Comparable sales**: 51 - **Sales from**: October 2024 – September 2026 - **Middle half of those sales**: $2,430,000 – $4,071,875 Based on co-op four-bedroom sales in Upper West Side. Square footage is recorded for only 20 of these 51 sales (39%), 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**: 95.6% (45 sales) - **Sold below asking**: 71% (45 sales) - **Typical time to find a buyer**: 89 days (46 sales) - **Typical time to close**: 97 days (46 sales) Based on co-op four-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. ### Price trend Median sale price, co-op four-bedroom sales in Upper West Side | Year | Median sold price | Sales | | --- | --- | --- | | 2017 | $4,577,500 | 16 | | 2018 | $3,050,000 | 18 | | 2019 | $3,850,000 | 11 | | 2020 | $3,500,000 | 15 | | 2021 | $3,603,333 | 27 | | 2022 | $3,225,000 | 26 | | 2023 | $3,375,000 | 21 | | 2024 | $2,455,000 | 24 | | 2025 | $3,475,000 | 24 | | 2026 YTD | $2,761,250 | 18 | Based on recorded co-op four-bedroom sales in Upper West Side. 2026 is year-to-date. Sales data through September 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.
