I accidentally in your base

For various reasons involving the size of the two rooms and the amount of stuff I want to fit in each, I'm considering using this flat's living room as my bedroom (bed, wardrobe, etc), and its bedroom as the living room/study (sofa, computer desk, etc). Because of the way the place is laid out, this would mean walking through the bedroom to reach the living room. I'm now trying to work out the pros and cons of this plan...

Pro:
* More space in new-bedroom, which means
  (a) I can have a king-size bed, with access to both sides of it (current-bedroom just fits a double, with one side against the wall)
  (b) I'll have more room for clothes storage - current-bedroom has one wardrobe and will start looking a bit crowded if I add a chest of drawers
* Less light in new-bedroom - current-bedroom has two windows, new-bedroom only has one
* Less noise in new-bedroom - one of the windows in current-bedroom (the one right next to the bed) opens onto the road and a footpath. People walking past talking sound like they're in the room with you.

Cons:
* Problems if people come to visit who I don't want traipsing through my bedroom
* Problems if someone is crashing on the sofa - they have to come through my bedroom to get to the loo, etc.

That's about everything I can think of so far. As far as I can recall, I've only had two or three people sleep on my sofa in the last five years, so I don't really feel a need to give that a very high weighting in my priorities. As for the thing with general visitors, I don't tend to have people visiting my home unless I'm quite comfortable in their company... so I don't think it will be a problem. Not 100% sure, but again to some extent there's the question of how much it bothers me on the odd occasion that I have a visitor, compared to the daily benefit of having a better layout for me to live in.

Does anybody have any extra cons I might want to consider before I start moving furniture around? :)
