The photos are really bad (poor angles, emphasizing furniture, etc) which is a pity because the house has lovely bones.
The orange tone of the wood trim is dated, and there's a lot of it.
Floor in the hall looks as if it could use some TLC.
The general decor is dated, and I know you can't do anything about this, but the general furnishing isn't in keeping with the era of the house.
Having all your couches pushed up against the wall and a vast carpeted area in the sitting room makes it look a bit bleak.
When I clicked on the link, the first photo was photo 1 of the kitchen, separated from the rest of the kitchen photos. I don't know if this is a problem for others looking at the site or just me.
Your photos should take you in order through the house.
Take the exercise equipment out of the bedroom.
If I were buying, I'd want to know if there were hardwood floors under the carpeting.
