# 323 East 21st Street #M-4, New York, NY 10010

> **Listing Courtesy of:** The Heller Organization Inc

## Description

Tucked away beyond a private courtyard is a rarely available one-bedroom home in a prewar co-op built in 1910 known as the Colonial Mews. A renovated windowed kitchen and en suite bathroom complement original details which preserve the apartment's charm, such as a decorative fireplace against exposed brick. With treetop views from both the living room and bedroom overlooking the courtyard to the South, and treetop views from the kitchen to the West, this corner apartment is uniquely private, as it is set back from the street. Additional features include two spacious closets, and thru-wall air-conditioning units in both the living room and bedroom.

Perhaps best of all, there is a remarkably liberal sublet policy, rarely seen in co-ops. After two years of ownership, unlimited subletting is allowed with co-op board approval. 

Kindly note that the apartment is located on the third floor of a non-elevator building (three flights up). Pets will be considered on a case-by-case basis. Shown exclusively by appointment only. Disclaimer: Some photos have been virtually staged.
