Not very well traveled yet but at the moment… either Prague/Praha in Czechia or Ljubljana in Slovenia probably
Both are pleasant places with beautiful architecture, all kinds of natural scenery as someone who has only lived in flat cities (mountains AND rivers in my city??). Bonus point that Prague has dirt-cheap beer that even comes in alcohol-free variety, Ljulbljana has a ridiculous amount of hiking trails and is within day-trip distance to some of the most beautiful scenery in Europe






The best thing… depending on how I ask I guess. Either the day trip I made to two nearby towns (one of which is a rather well-known tourist spot) on Sunday despite the rainy weather, or the fact that weather rose to 20 C yesterday & was sunny so I made a nice stroll in the city
