121 E 23Rd St

A full-service mid-rise condominium completed in 2005, this 21-story building contains 34 residences configured primarily as studios, two- and three-bedroom homes. The exterior reads as a contemporary Manhattan residential block with a stepped roofline and private terraces on select units; many homes offer multiple exposures and city skyline views. Interiors emphasize gracious circulation with formal entry foyers, dedicated dining areas, and generous walk-in closets; several units include in-unit washers and modernized kitchens and baths from recent renovations. Shared spaces include a landscaped courtyard, a planted roof deck and a residents’ terrace that extend living outdoors, plus a resident lounge and a fitness room. Building services are full-service: 24-hour doorman/concierge, elevator service, bike room and central laundry support daily life; valet and on-site management have been offered in past listings. The property is pet-friendly and permits flexible financing and ownership structures, accommodating pied-à-terre and foreign buyers. Located on East 23rd Street at the Flatiron/Gramercy edge, the building sits steps from Madison Square Park, transit hubs for the 6, N, R and multiple subway lines, and a dense neighborhood of restaurants, markets and retail.
