The photo's aren't the best. They make the living room look a bit cold and colourless.
Can you move the sofa's so they are facing each other?
The photo's make it look like everything is pushed back against the walls, so it looks a bit empty in the middle?
If it's possible to have the sofa's face each other, with a warm toned rug in the middle and perhaps a low table, I think it might look like a cosier space, especially if you get some cushions in warmer tones as well to compliment the rug.
If you can't move the sofa's, I still think a low table, rug and warmer looking cushions or a throw might help to fill the empty floor space a little and warm up the room.
I might also be tempted to take down some of the framed pictures in the living room, they do dominate the wall a little in the photo's. The one's in a group of six on the small wall maybe.
What's the big thing under the TV in picture 2?
Can you move the toy kitchen for the photo's? And the big dog head thing on the chair?
In picture 3 you can see a pile of stuff hidden at the side of the sofa. Can you move it for the photo and then put it back, just so the space doesn't look cramped and used for storage of stuff that can't go anywhere else.
In picture four the kitchen is mostly lampshade and wall. It shows a space but you can't really see much of the actual kitchen.
The lampshade and hanging pans are nice but not what people need to see.
I'd unplug the appliances and hide the wires as well.
It does look like a nice warm room though, but you need the photo's to show more of it. Even if that's just having a photo from another angle added to go with this one so people can see both sides.
Picture 5 does need the bed to be shown off a bit better. I agree about tucking a throw into the bottom third, and maybe having the pillows on top of the duvet rather than under it. At the moment the photo does just make it look like the bed is covered by a dust sheet that dominates the space.
I'd also move most of the stuff on the shelves and unit opposite the bed, so it looks like a tidier space for the photo.
And if they have to pull a curtain across, maybe it should be the one that shows how the balconies outside can see into your bedroom.
You need photo's of the bathroom and balcony, and if you have a nice table or chair out there, and a plant or something, to dress it up a bit then that can't hurt.
They need to take the exterior shots and balcony one on as sunny a day as possible.
I would also have a proper price rather than an "offers over" price. Vague prices put people off, they worry about bidding wars or offering more than you are prepared to take.
