I want to give them the benefit of the doubt and say perhaps it’s a deep freezer that is only opened occasionally, and I guess is pretty well sealed as long as it’s closed.
The kitchen appears to have one of those built-in fridges that matches the cabinets:
“Big enough house” doing a lot of work here :)
Not that it’s a bad thing, I think anyone would like having a wash room if given the space. Still better having a washing machine in the kitchen than going to the landromat down the street.
