In the first half of January, I'm planning to go on a 3-4 days city sightseeing trip in Europe. I'm looking for a nice location, but I'm not so sure which places are a reasonable choice in winter. I prefer to do some sightseeing, museums and other stuff like this I don't like very much, expect they're extraordinary good.
I would like to visit a city that has a lot of sights that can be visited also during winter and it shouldn't be too crowded. Additionally I should be easy reachable from Switzerland. Because the weather is often not so stable in January I would prefer a city that also offers some indoor activities.
Has anybody a good recommendation? The following cities I don't want to visit: Lisbon, Madrid, Paris, London, Munich, Berlin, Stockholm, Oslo, Riga, Tallinn, Helsinki, Moscow, St. Petersburg, Budapest and every city in Switzerland, Italy and Austria.
