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:
Where else would you put it? Might as well just place it next to all the other appliances. We do it in Germany too, pretty sure it’s just a European thing.
At least in Finland the washing machine (for washing clothes) is usually in the bathroom/shower room, like in the photo in this post.
Finns also have saunas in their home, which is awesome but not really standard anywhere else.
Never seen a wasing machine outside a bathroom or a washing room if your house is big enough here in sweden
My family/me (in and around berlin):
Me: WM in the kitchen
Parents: WM in the bathroom
Brother: WM in a little nook on the corridor(? Flurnische)
Another Brother: WM in the basement (benefits of a house)
