A taxi ride from the airport to the Old Town of Vilnius takes approximately 15-20 minutes. Taxi companies which provide service in the airport area may charge a higher rate than in the city, so we recommend to order a taxi by texting a sms to +370 633 44553 with the following text: Vilnius airport to hotel address. You can also use taxi apps (taxify, etaksi). If you want to travel using public transport, you can take the bus 88 to the old town.
On the website http://www.vilnius-tourism.lt/en/ you can find more information about public transport, car rental, taxi etc.
