I like the house, but it doesn't feel cottagey, which considering its major plus point is that it is a character property, is missing a trick, I feel. All the furnishings are inappropriately modern and too bland - that grey chair, purple rug and sea picture in the lounge, for instance.
I'd get rid of all the modern bits where possible, take down all the pictures and ornaments and baskets and wall-hangings and clocks and especially that blanked-out picture in the lounge, presumably a family photo. If it's too full of the current owners' family, viewers can't imagine themselves living there.
The child clutter makes it look very unappealing, and the weird wooden thing at the base of the steps is very ugly and makes it feel too dangerous for children. With only 2 bedrooms, it's really too small for a family, so unless it's much cheaper than local 3 bedroom places I can't see a family buying it. I realise it's hard to clear kiddie clutter when kids live there, but it would increase chances of selling if the toys are put away.
Agree 100% with PP that the brown wall does the main bedroom no favours. And that cushion on the bed looks like a strange slug and doesn't match. Is bedroom 2 big enough for an adult single bed, because it doesn't look it?
