Traveling to Bogota, Colombia?

So I'm a 17 year old Canadian Male. In Febuary I have a very close colombia friend coming to Nova Scotia for a student exchange and her family invited me to fly back with her and stay with them for awhile. Her family is very rich and lives in the safe part of Bogota and I trust her very much.But I'm wondering how safe it is in the Streets? Does anyone have any tips for me for flying or buying or eating?
