Sleeping in this hotel in summer = impossible. We couldn't sleep through the night and tormented ourselves for hours with the enormous heat on the fourth floor. Only half of the rooms are air-conditioned and when we asked for a fan, we were offered a small table fan that didn't help. The rooms weren't cleaned once during our two-day stay and the towels weren't even touched. Breakfast is plentiful, but no distance is taken here. Only the free parking and the good location directly on the motorway make the hotel a two star hotel in my eyes. I don't understand on what basis the hotel was given four stars when the most basic, sleeping, is impossible in this hotel.
