Description

NEWLY RENOVATED FULL-FLOOR DESIGNER PENTHOUSE AT CASSA RESIDENCES

Welcome to PH1 at Cassa Residences, a newly renovated full-floor designer penthouse in the heart of Midtown Manhattan. 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.
