There was a turbolift map visible at the lift our heroes took to that reception facility in ST:Insurrection. It showed, with a bright dot, the ride going from the bridge down and aft, and there's indeed a set of suitably slanted windows on the specified Deck 9 at the spine of the ship - just aft of the dark band below the shuttlebay area. That's where the reception supposedly was held, then.
But any glowing spot on the exterior of the hull can be a window or a deflector or a sensor dish in Trek; we still debate on the nature of the round glowing things at the bow of Kirk's ship, say.
