Various members of my family have lived in or on the outskirts of Brighton for many years now (we're also from the north). I was just there a few weeks ago with my daughter, and have to admit it did not live up to my fond memories of when I was younger & childless. I found it an unsuitable place for young children; the pier is a meeting point at night for brightons's youth culture and those who really should just 'get a room'. A very expensive place, and whilst some of the accomodation is exclusive, some is also very run down & dirty. There are an awful lot of drugs floating round (as with most city centres unfortunately), but personally, I found the place dirty. The surrounding towns ie rottingdean/seaford/peacehaven are beautiful, scenic and certainly less expensive. I am mid-30's so not too old to kick my heels over my head, but found the centre too much. I considered moving there a while ago, but would personally move to Seaford (approx 10 miles out) & flit into Brighton when I was feeling wild!!
