In 1972, in NYC, Queens I was looking for an "efficiency" apartment. There was one in a tall apt. bldg.It was 7' wide and 12' deep with one small window at the far end. In that space was a tiny closet and shower/sink room/toilet room. I had a couch/bed and one of those cook & wash refrigerators for $400/month. No. I didn't take it. Even a sardine would have felt cramped in there.
