I live in a first floor flat with nobody above me. I've been awake since 5am, my nesting instinct has finally kicked in at 37 weeks and I feel the need to clean! More specifically hoover. I'm aware that the sound proofing isn't very good between my floor/their ceiling, although next door can't hear anything from me. I know downstairs aren't up yet so I'm not going to start now but any clues as to when would be acceptable, regardless of whether they're up or not?
