18 East 18th Street, also accessible via 22 East 18th Street, is a historic pre-war co-op building constructed in 1900 and converted in 1988. Located in Manhattan's Flatiron district between Broadway and Fifth Avenue, this boutique building rises 6 stories and contains 10 full-floor loft units, featuring two separate lobby entrances with video security systems and keyed elevators.
The residences are characterized by their authentic loft features including soaring 12-foot tin ceilings, original Corinthian cast iron columns, hardwood floors, and massive windows providing abundant natural light. Units typically offer flexible, open floor plans with private elevator access, and many have been thoughtfully renovated to incorporate modern amenities while preserving their historic architectural details.
The co-op is pet-friendly, allows 70% financing, and permits subletting for three out of every seven years. Building amenities include a part-time super, bike storage, and a common roof deck. Its prime location provides easy access to both Madison Square Park and Union Square, along with the area's renowned dining, shopping, and transportation options.

For some co-ops, instead of price per square foot, we use an estimate of the number of rooms for each sold apartment to chart price changes over time. This is because many co-op listings do not include square footage information, and this makes it challenging to calculate accurate square-foot averages.
By displaying the price per estimated room count, we are able to provide a more reliable and consistent metric for comparing sales in the building. While we hope that this gives you a clearer sense of price trends in the building, all data should be independently verified. All data provided are only estimates and should not be used to make any purchase or sale decision.
