It's a bit more than an hour since I returned from a lovely trip to Estonia, and I want to start with the freshest impressions. Those come from Tartu, the second largest city in Estonia. Tartu is known as a student city with a laid-back character. Everything is more or less within a walking distance, so Tartu people consider everything far if it can only be accessed with public transport. Tartu is biking-friendly, with many comfortable open spaces.
