I enjoyed Helsinki big I found the Finns to be rather morose. Of course, it was in the beginning of October and the temps were already at the freezing mark. Tallinn, on the other hand, is full of the cutest blinds I've ever seen. There are a few clubs in the Old Town. Most of the Millennials speak English well, so you won't have a problem communicating. Next time I'm there, I want to visit Latvia, Lithuania and St Petersburg.
