A snug is a small room or space that is cozy, comfortable, and warm. It most often refers to a small bar-parlour in a larger inn or pub, but it gets plenty of use as a reference to a cozy den or comfortable lounging area in a house, apartment, or lodge. It's short for snuggery, a term that dates to at least 1727 (the OED's earliest is from 1812, so this is a significant antedating).
