If I'm correct 1100 is a corner aft Junior Suite. The balcony can be seen (from below) in those two photos:
It seems to be rather big, so I think it's a great location.
Only issue may be that it's rather open from above which can be seen here.
This is not exaclty the same balcony but another one on deck 10. Even if a part of the balcony is visible I don't think that will be a big issue, as the outdoor part of the Windjammer is directly above and there people are mostly sitting and eating and not standing at the railing looking down.
