I don't think it's the weirdest house I've ever seen. The teeny kitchenette when there would have been space for a better kitchen was a poor choice in terms of resale-ability.
The bath in a bedroom - well, I have seen that sort of thing in ultra-trendy penthouse/loft apartments, it's meant to be like a suite in a hip hotel, but it's strange in a bedroom that's scarely big enough for a double bed and some storage.
Calling a cupboard less than 6m2 a bedroom should be considered really strange, but isn't, sadly.
