It does look a bit shabby. But if it’s up to code, insulated properly and has a bathroom I’d take it. I’ve seen worse “traditional” 1 room apartments for more money than that.

I may be wrong on this but I’m pretty sure I’ve seen some seemingly redundant “no gluten”, “lactose free” or “vegan/vegetarian” labels on a lot of products in german and austrian supermarkets. Could be that these products are labeled that way because they were made in an allergen free environment i.e. no parallel production of something containing these allergens.
