小胖鱼largeVilnius Tallinn and Riga, I still like Vilnius the most. The other two old cities are too small. Vilnius’s old town takes a whole day to walk, and there are many coffee shops. It's already very cold in autumn, and the opposite country is worth your visit. Public transportation is not needed. Walking is the best way. At night it is very quiet and there is almost no nightlife.
