I live in Lithuania and I guess it was the same here, as all apartments have thick steel doors with multiple locks, and ground floor apartments of older buildings often have bars.
Now though it's nothing like that. I'm originally from the UK and I feel much safer being here. Not only personal safety (I don't feel there's any 'bad parts' of the city you 'shouldn't go') but also private belongings. I've never heard of anyone in recent times being burgled or having their car broken into.
Live in Poland, muggings aren't really a thing, and according to the "what worries the world" monthly polls of ipsos[0], poles are the nation that least worries about violence and crime (it was surprising for me to see the effect is that strong), with only 5% worrying about it.
