If it's a balcony cabin there will be a balcony to sit on. But give us your ship and cabin and I bet someone can give you a real good answer, Perhaps even a photo.
That is a real good answer based on the information provided.
There are differences depending on which ship it is. The basic definition (excerpt from Carnival) is "View is obstructed by a lifeboat, tender boat and/or steel beam".
Boneman, please give more specific details about the ship and cabin.
