I have no experience of living in higher-floor flats besides Friends and other TV shows. I've always thought that burglars wouldn't pick flats on higher floors because it'd be more difficult to carry their loot back downstairs. Plus there'd be more chances of coming across someone.
Can anyone who does live, say, on the 8th/tenth floor and up share any knowledge they may have of this? I have no need for this information beyond that to satisfy my curiosity!
