Offering over 2,500 square feet, four bedrooms, three and a half bathrooms, and spectacular views from every room, this is one of the rare opportunities in Midtown that combines true penthouse living with serious investment upside. PH1 is not a standard condo. This is a private full-floor residence with quadruple exposure, open skyline views, river views, and incredible natural light throughout the day. The 41-foot great room anchors the home, creating a dramatic entertaining space surrounded by oversized windows and a constantly changing New York City backdrop. The windowed eat-in kitchen features modern white lacquer cabinetry, Pietra Bedonia stone countertops, and top-of-the-line appliances. Each bedroom is generously sized, with multiple rooms offering double exposures and strong views. The primary suite feels like a true retreat above Midtown, while the spa-style bathrooms feature Glacier glass walls, limestone floors, Travertine marble vanities, glass-enclosed showers, soaking tubs, and refined designer finishes. What makes PH1 especially powerful is the rental strategy. Cassa allows flexible 1 to 12-month leases, and large four-bedroom short-term/flexible rental inventory in Midtown is extremely limited. For investors, corporate housing, executive stays, relocation clients, and high-end furnished rental demand, PH1 offers a rare product type that is hard to replicate. The four-bedroom layout creates a major advantage because most flexible rental options in Midtown are smaller units, making this residence stand out for premium tenants during peak seasons and high-demand periods. Cassa Residences delivers a full-service luxury lifestyle with 24-hour doorman and concierge, hotel-style services, fitness center, business lounge, landscaped outdoor terrace, private event space, access to the acclaimed Butter Restaurant, housekeeping options, dry cleaning, and additional lifestyle services. Located at 70 West 45th Street between Fifth and Sixth Avenues, PH1 places you moments from Bryant Park, Rockefeller Center, Fifth Avenue shopping, Times Square, Grand Central, top restaurants, hotels, offices, and transportation. A newly renovated full-floor Midtown penthouse with four bedrooms, massive entertaining space, privacy, views from every room, and rare 1 to 12-month leasing flexibility. Whether used as a luxury residence or positioned as a high-demand furnished rental, PH1 is the type of asset that is almost impossible to replace in this location. ## Property Details - **Property Type**: Condominium - **Beds**: 4 - **Total Baths**: 4 - **Rooms**: 8 - **Sqft**: 2,580 sqft - **Stories**: 48 - **Year Built**: 2009 - **Price per Sqft**: $5,814 - **Common Charges**: $3,527 / Monthly - **Listed On**: May 21, 2026 - **Days on Market**: 110 Days ### Residence Features - Central Air - Building Other - In Unit - Building Roof Deck - High Ceilings - City - Park/Greenbelt - Ocean - River ## Sales Evidence ### Recent closed sales 2 apartments at Cassa Hotel And Residences have recorded sales since September 2021, the most recent for $1,170,988 in April 2026. Prices are the figures recorded with the City, not asking prices. | Unit | Beds | Sq Ft | Sold Price | $/ft² | Sold | Source | | --- | --- | --- | --- | --- | --- | --- | | U 30C (Apartment) | — | 584 | $1,170,988 | $2,005/ft² | April 29, 2026 | City record | | 31C (Apartment) | 2 | 558 | $1,100,000 | $1,971/ft² | November 24, 2025 | 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 The median closed price for comparable condo four-bedroom sales in Midtown is $16,462,500, based on 8 sales between March 2025 and March 2026. This home is asking $15,000,000, $1,462,500 below that median. The middle half of those sales closed between $10,309,738 and $23,500,000. - **Median closed price**: $16,462,500 - **Middle half**: $10,309,738 – $23,500,000 - **Based on**: 8 condo four-bedroom sales in Midtown - **Period**: March 2025 – March 2026 - **Median $/ft²**: $4,450/ft² Across the 8 of these sales with a published asking price, the median closed at 83.6% of what it originally asked. 100% of them closed below the original ask. This building has not had enough comparable sales of its own in the period to support a median, so the benchmark is drawn from Midtown instead. ### How these sales were negotiated - **Sold vs original ask**: 83.6% of the original ask - **Closed below ask**: 100% of 8 sales - **Listed → in contract**: 138 days (about 20 weeks) - **In contract → closed**: 79 days (about 11 weeks) Across the 8 of these sales with a published asking price, the median closed at 83.6% of what it originally asked. 100% of them closed below the original ask. Half of these homes were in contract within 138 days (about 20 weeks) of coming to market, based on the 8 with a recorded listing date. Once a deal was agreed, closing took a further 79 days (about 11 weeks), based on the 8 with both dates recorded. 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. Based on 8 condo four-bedroom sales in Midtown, March 2025 – March 2026. Each figure counts only the sales that recorded the dates it needs, which is why the denominators differ. 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.

We calculated the tax for those years using the prior year’s rate, so treat them as an estimate rather than a figure the City has adopted. Every rate without the Estimated marker is the published one. Tax Assessment is the assessed value on the City’s roll, and it is the figure other listing sites publish. It is not what the bill is calculated on. New York phases assessment changes in gradually for some tax classes, so the City bills the Billable Value shown beside it, less any exemption the owner holds. It usually trails the assessment, and it can sit above it for a few years after an assessment falls. Figures are the New York City Department of Finance assessment roll for tax lot 1012601154. Assessed and billable values are determined by the City for tax purposes and are not an appraisal or an estimate of market value. Tax classes and rates are set annually and can change.
