Is that your house with the awkward shape front garden?
If so, look at your end-terrace neighbour. Their frontage is clean smart and neat. It says "this home is well cared for, we take pride in maintaining it."
Your front garden is weedy and neglected; even the bins are untidy. It gives a message "We don't enjoy living here and have no interest in taking care of it>" You need to tidy it up, make it look more welcoming and less abandonned. Especially if the back garden is as tiny and unattractive as her description sounds.
It's a family house that says "nowhere for the children to play ".
What a pity the agent didn't meantion the nearby park.
Frankly I don't think much of your agent. She should have drawn the front mess to your attention. There is no excuse for not offering a floor plan and the Council Tax band. Or a link to the Home Report.
She's giving viewers a lazy message "I don't give a toss about promoting this property".
