It’s probably a good idea to start off by saying that this quirky co-op at 228 East 13th Street is comprised of 300 square feet of interior space. That’s about the same as the “large” model in most luggage sets. Ok, it’s actually bigger than a suitcase, but not by much; that fact aside, there’s a lot you can do with a small space. And if you’re going to live in one, it might as well be a good one, in a great location–like a gorgeous brick-and-brownstone block of the East Village a few blocks from Union Square and actually near subways. With something special–like a sunroom.
