Lately femecide has been happening more often. Nit scared of getting robbed necessarily but not comfortable being alone outside at night. Also cat calling happens at night and men following especially in city center

Leeuwarden is very save you can walk alone in the city every body you see is nice and I have never experienced a bad situation. One time there was an attempt to break into my home. But it wasn't successful.

I would say Leeuwarden, being the capital of Frisia, is a safe place. At night, don't wander of too much of the centre if you want to be sure. There are some parts, like every city, that I wouldn't go alone in the dark. At night there is plenty of security around the bars!
