I'd ask for a high floor. The top is 8. However, the balconies on 8 are open to the sky and, if you leave something (like a computer or an iPhone) on them and it rains???
Better to ask for floor 5, 6 or 7. The balconies on those floors are covered by the balconies above them. They are high enough for great views.
