It's nice little house for someone looking for a nice little house.
It could be fantastic with some time and money but first impressions could be improved very easily.
Livingroom - get rid of the ornaments, is there an elephant hanging from the ceiling?! Put away the remote controls and plump the cushions, why would you allow an agent to take it like that/why wouldn't the agent tell you?
The bedroom is fine IMO, I quite like the brown wall although dated. Not sure what the spotty thing is.
Garden needs a really good clean and tidy, it could be beautiful - my dream is a stone courtyard garden. Jet wash, get control of the ivy, be more selective about the pots and plant them up properly. Small table and chairs.
Clean the front steps! And either get bigger nicer pots or get rid of the pots.
Make the basement look like a proper grown up living room - I like the suggestion to move the table upstairs, no-one fancies carrying dinner downstairs, as evidenced by the table looking unused and cluttered. Hide the toys. Plump cushions put away remote controls!
Get rid of the first kitchen picture, it looks much better in the second, they don't need two.
Bathroom isn't going to be to modern tastes but apart from taking down the curtain, not much can be done easily there.
You can see clutter on the windowsills from outside, get rid.
That said, whether it's worth £100k or not is what will really make the difference.
