I don't remember any extra window. It would mean you have a staircase on the otherside of the wall - I don't know if this would generate any extra noise.
we stayed in a corner room last october it was only for 1 night, and as said, the stairs were on the other side of the wall. we didnt hear any excessive noise and would stay in that room again. i think if you had a room on either side of you it would maybe be a bit noisier.
