The streets are full of colorful and historical buildings. I really recommend to visit the church and take the stairs all the way up to the top to see the amazingview over the whole town. There is people selling souvenirs in every corner and doesn’t approach to you unless you do so. What I really also loved was that you could fine free guides almost every where in the old town that speaks German, English and Russian. Really cozy place with amazing vibes all around.
