I'm with everyone else who's said your photo of the front is better than the EA's, although it needs to be one without a car parked there.
It's a lovely house, nicely presented inside but the driveway needs a jet wash and the back garden isn't selling an aspirational lifestyle to match the interior, imo.
I imagine that apart from the current state of the market having a detrimental effect on the higher end of the market (nothing near us over £1m is selling), there's a couple of other factors you can do nothing about....
Firstly, the bus stop - years ago we owned a detached with bus stop outside. Not only did we get less viewings than a neighbouring house without the bus stop, but had to take a (small) hit on the price despite ours being recently renovated whilst theirs was not.
Secondly, the external steps. Again we have experience of this! Our last house was a converted mill with an undercroft beneath the raised ground floor, as a result of which there were ten stone steps leading through the front garden to the door. Our EA warned us that it would deter some buyers when we sold in 2024 and they were right. No-one viewed who had babies/young DC and our only older viewer - who was initially extremely interested/had a second viewing - eventually decided not to offer because of the access issues.
Your pool of buyers will undoubtedly be reduced, but as you've already had a reasonable number of viewings (we only had around eight over six months for the mill) and an offer, it's obviously not putting everyone off! I wonder if the fact that the ground floor overall seems disproportionately small for a five bed house when they see it in real life, is the stumbling block? Could a buyer convert the basement rooms to habitable space - eg, a cinema room, or are the ceilings too low?
