Ive had a few as I rent! Luckily ive always had decent landlords and managed to dodge the worst kind of neighbours, but when you get a bad one, it can mark you for life!
Worst for me was living in a gorgeous house but next to a Lidl delivery bay, OMG. There were frequent midnight and 5am deliveries that shook the entire house for over 2 hours. Eventually after I left they had to construct a deadening wall which the neighbours still claim is useless.
How about you?
