We had a dedicated BWV studio twice, once on the 3rd floor and once on the 4th floor. Both of them in the same section over the games (one on top of each other). The 3rd floor unit had a solid wall which was disappointing. I couldn't sit and watch the crowds. The 4th floor one had a regular balcony.
Here's a picture of the 3rd floor one:
We really liked the view and if I was going to spend preferred view points anyway I would go for the Boardwalk View. The only negative was the DING! of the games outside our door. We could hear them even with the door closed.
