Carter's Review

This handsome, 12-story midblock apartment building at 260 Fifth Avenue between 28th and 29th Streets was built in 1900 and has 49 cooperative apartments.

The building has a limestone façade and quoins and a large bandcourse at the 10th floor.

The building has a full-time doorman, high ceilings, an elevator and is pet friendly.

One of the full-floor apartments has 33 windows as the building has many "lot-line windows."

It is half a block south of the very handsome Marble Collegiate Church and a couple of blocks north of Madison Square Park.
