Never experienced a crime during the day would not be running around alone at night though because of feeling uncomfy (there was a homeless man that got beheaded a few years back) otherwise just the normal disgusting men trying to get some but keeping it harmless. Otherwise mostly nice older ppl helping you find your way if you ask

if you know how to avoid certain areas at night (koblenz main station where the crack addicts are) and stay in the old city to party, you're okay. there might be some weird men out in the city, but not more than somewhere else in a moderately small european city. i've been walking the city alone at night since i've been 15 and nothing ever happened- however in bars, men might be a little persuasive, so be careful not to talk to just anyone.

Nothing big ever happening here. It is a generally quite safe area. I think it is typical to say that you should be cautious no matter what, especially as a woman late at night, but if you follow your gut, you will be alright.
