What's the highest floor you have ever lived on? How was the view?

I spent a chunk of childhood living on the 12th floor of a building that had 13, near Antwerp yet far from the sea. There was nothing better than seeing a rainbow across the old factories and brick storehouses - if that is indeed what they were, for I never seemed to venture that way on street level. It was only ever a backdrop, with no people in sight.
