We are vampires. My young family sleeps in the basement rooms of our flat, which takes up the bottom two floors of a Victorian terrace.
Down in the basement it is cool and dark, which is lovely in “summer” but horrid in winter. It is quiet, though; womb-like often. Dehumidifiers and air filters ward off worries of damp and mould down there, but I do worry if sleeping in the basement is psychologically disturbing.
