OK, Kirsty and I have been chatting (constantly) about this photo...Kirsty doesn't think it looks 'lived in'. She is intrigued by the symetry of the doors and chairs and that the room has a lack of personal items (except the photos) and no visible wardrobe, which would have been a necessity for the long coats or gowns of the time. However, if this is staged photo, then you don't have beds hanging around and if this is either an attic or cellar, you aren't going to drag beds up/down stairs for the photo.
My feeling is that it could be an amature photographer who just wanted to photograph the nearest thing to hand, so he set his (or her...) room up. I know that when I get a new camera I just start taking photos of the closest thing! This could explain why the room doesn't quite look genuine - it's been quickly re-arranged and tidied for the photo.
Kirsty raised another point when we looked at the photo: in the room, there are 5 identical chairs (2 in the foreground on either side of the room and 2 next to the dressing table, 1 on the left raised level - is the ghost sitting on the 6th?!?!?!). It seems unusual that you would have that many identical chairs in a bedsit.
Literally as I type this....my idea is that the table in the foreground with the photos on is in fact a dining table (presence of candles too?). It would most likely have a table cloth and we can't see the legs or if it is a desk with drawers? I'm just thinking out loud here I guess...

I'm still not sure about the presence of a second bed. If you look at the opposite side, there is a just enough room for a chair and a chest of drawers, leaving access to the door (which makes me think the door is in use). So I don't tonk you could actually fit a bed in, not leaving access to the door anyway. Kirsty disagrees....
Sorry for yet another long post with lots ideas as I think of them...
