Was comparing Crystal and Monopol, there is none. Monopol is the clear choice if you wondering which one to stay at and you value a younger crowd, cleaner and modern hotel, design, better view, better service.
Could see the lake from my 5th floor room. Offered Prosecco when checked in, hot tub (dedicated hour per room during COVID) and sky bar is great (reserved for guests only during COVID so no one there).
Modern, fresh, clean, friendly, great view, bars and right on top of all the nice stores, what more can you ask for?
