I think it's a wonderful house, with great spaces and a real bonus that there are three more or less equal sized bedrooms as well as the master suite. It's beautifully presented as well.
I do agree with the previous posters' suggestions for tweaks especially painting the front door a dark and sleek grey to modernise it in keeping with the interior. A couple of pots with either some winter colour or some standard shaped plants will also improve first impressions.
If I had to be picky, as well as removing the photo showing your immediate neighbours, I'd restyle the family seating area by the stairs. Is there a TV perhaps in that white unit that we can't see? Can you photograph from the opposite angle, just up the stairs maybe?
If space allows, I'd be tempted to take out the breakfast bar stools and put the two arm chairs and table under the window opposite, because it's obvious you can put stools there if you wish, but under the window's a bit of dead space (unless it's smaller than it looks)
Put something more welcoming by the stairs, a small sofa and coffee table perhaps, if you can borrow, or source from ebay? Just to demonstrate how spacious it is and how those areas are adaptable according to a purchaser's requirements.
Good luck.
