Vilnius has one of the biggest old city centre in Europe. Around lots of green and the bohemian district of Uzupis highlight a pleasant medium sized town. Unfortunately in winter can get really cold
My impression of Vilnius after a few days was good. As the capital of Lithuania with about half million inhabitants, it's got a unhurried vibe. It's not crowded with tourists, because there are only a few sites to see. But that shouldn't stop you from visiting this beautiful city with nice architecture. Don't forget to visit the Republic of Uzupis, across the river, which is the city's Bohemian district of artists. The pubs of Vilnius along with its beer gardens are a fun and inexpensive way to get a taste of the local culture and delicious Lithuanian beers.
Vilnius was a pretty cool capital city. Although a long way from the airport into which we flew (Ryanair), it was definitely worth the trip. There is a ton of culture here sprinkled among the residual Communist architecture. Everyone with whom we interacted was very nice and helpful. If you're into fossilized amber, I got the impression that this was the place to pick it up.
Unfortunately I can't write a rave review of Vilnius. I took a trip through the Baltic States - Vilnius to Riga to Tallinn and Vilnius was by far my lease favorite. Teh sites weren't as impressive, the people weren't as helpful and the food was just okay. If you are heading to Vilnius, I don't think too much time is necessary.
