I prefer V2 because I also find it nicer if the staircase is not the first thing you see when you come in, however I would mirror the staircase so that the bottom of the stairs comes first. And I would also make the hallway a bit wider. I think the living and working rooms can easily afford a few centimeters less in width. We have a 1.2m wide fairly long hallway and if there is nothing there it is okay in terms of width, but as soon as there is, for example, a piece of furniture, it becomes very tight.
