There are no photos upstairs. It makes me think it looks horrible up there.
The decor is very dated, and the furniture (the little you can see of it) looks cheap, especially as there are now flowers, no table runners, no candles, to distract from this.
I would move what has inevitably become the focal point of the kitchen : the bit chrome drying rack out of the way, along with the booster seat.
I would add a bowl of fruit in kitchen. And a table runner and a flower vase.
I would weed, add nice colourful big pots of flowers by the front entrance (those you take with you when you move)
The only thing I find really offputting, is the tv on the wall. I straight away think redecoration costs and to fill in the holes. It also makes me think the room is too small to have a tv anywhere else.
It is a great fireplace in the living room, and having a tv, rather than a mirror above it, really ruins it.
I agree the house looks cold and uninviting. I would not view it.
