@23 It wasn't a corner building. A couple of houses in from 23rd, on the south side of the street. Or maybe I'm off by a block. I don't remember the address.
The apartment was so cheap because it was in the basement, with radiators and pipes in a low ceiling. But it had access to a little patio in the back.
Only thing else distinguishing I can tell you is that there was this elderly, retired, bachelor attorney who lived in one of the apartments upstairs, and who had lived there forever. He had no idea where he was going to go. It was very sad. And the new owner was a total dick about it. When I called to complain that workers had clogged the sewer so that it backed up into my shower when somebody upstairs flushed the toilet, he laughed "so sue me," and hung up the phone.
