That is the most forward cabin on Panorama Deck starboard, on the Dream. It's not in the back. Looking at the images on Google, that cabin has the standard window like you have in any other outside cabin with no balcony. Google Carnival Dream images and find some of the front of the ship. That cabin is on the outside of the first "white" deck below the tinted windows.
It is not floor to ceiling from what I see.
