You can find a 2-star in Z rich for about twice as much, but don't expect an equivalent room. There are three factors at play.
Rooms are usually smaller, less brightly lighted and perhaps somewhat less well furnished.
There are many exceptions, especially if you like authentic antiques. In cities you may find more noise. Air conditioning is uncommon. Your trip would be cheaper if the Swiss had spent the last 30 years mortgaging the future. Today, you'll get about a third as many.
