I quite fancy a city break in September/October. 4-5 days somewhere city central with places to visit (ie cultural/history/outdoors) with reasonable weather. Maybe part of a tour.
Thing is I don't know where I'd like to go! Over the years I've been to Berlin, Cologne, Innsbruck, Tallinn, Warsaw, Florence, Helsinki and Copenhagen. I'd like to pick somewhere I've not been before.
Any recommendations?
