Regarding mannequins....... at our previous rental, which was quirky (aka in piss poor repair but cheap for size and location) we had a large unkempt and secluded garden. Had you visited you would have been greeted with half a dozen mannequin torsos sprayed matt black and sporting obsolete video cameras as heads. We're a bit "creative" lol.
In side you would have met a mannequin sporting DPs old re-enactment armour, festooned with fake ivy and fairly lights in the shape of skulls plus red fabric ties in strategic positions.
We rigged a bar in the front room using a black sprayed coffin with a perspex lid, that contained a black sprayed skeleton clutching a funerary violin against a red lining.
Happy days - in the summer we put up a medieval tent with solid chequerboard flooring to entertain.....
We no longer have a garden, but our bed is a black four poster constructed from scaffolding with a canopy of decorative swords.
It's just us, but most people seem to appreciate the quirkiness 
or they're just being kind. But we like it
