As a local I can confirm, Vilnius has became very strong with its startup community. A lot of international businesses are moving in, a lot of big companies are already in. And that all gathers around the smaller companies and startups.

Super cheap 1-gig internet, super cheap unlimited data mobile LTE / 5G, great food and people. Accommodation is somewhat average, 500-600 euros for a flat in the city centre on average.
