If you travel to Vilnius, you can spend one day in the city of Kaunas. It's still nice to visit another city. Around the Town Hall, a lot of cute streets with an old architecture. From here, you can walk into the St Michael the Archangel Church. It's not really far. This is the main axis of the city.
How can I define Vilnius in few words ? I will say: architecture, churches, heritage and quietness. Vilnius is not a crowded city. When you will visit this city, you will appreciate the quietness of the places. I advice you to visit first the main avenue : Gedimino Avenue. From it, you will reach each interesting places to visit. One of the famous place is the Gate of Dawn. The people are welcoming and the food is tasty. A long week-end is nice to visit this pretty city. Be careful, the winter is so cold. Another idea to spend time is to walk along the Neris River. But it's better in the summer.
