Pete;

Not sure _why_ you'd want to walk the streets at night, unless this was a stroll along the corniche - most places are a long way apart so driving is required.

But yes, it is certainly safer here than in 90% of cities in the UK.

You could even say that it is safer to walk at night than drive at night :-)))

Meeting other people depends on your social outlook - it helps to be outgoing! ... doesn't it always. There are plenty of social venues which provide opportunities to meet people, depending on your interests.
