Nihilus is right: the windows ARE large, but only because the interiors of the ship are fairly large. The diplomatic decks of the ship are each 6 meters tall, instead of the usual 3. This gives the saucer only 15 decks; 6 of which are the 6 meter variety, the rest being 3 or 4 meters. Interestingly enough, the Atrium (the forward room with the oval windows) is located on decks 10 and 11! The first 7 decks are mainly quarters for the crew and command staff. Decks 8 through 13 are the diplomatic decks, each with its own atmosphere controls for different environmental conditions. Decks 14 and 15 are also crew quarters, but more for enlisted than for officers of any kind. Steerage would be an appropriate term for this area.
