Trish, I wish you had contacted me about your concerns, instead of sending your list of grievances the moment I had departed [after what had been in my mind a quite pleasant, uneventful weeklong stay].
I left on an outdoor light in the afternoon in anticipation for returning at night to a fairly dark side street. I sometimes left on the bathroom fan to keep that room from getting musty.
My itinerary from airbnb concerning my stay said 'Flexible Checkout'. You may want to check that out to avoid future misunderstandings.
[Despite these hiccups, it's still a lovely flat!]
