I can see why it hasn’t sold, it’s very much personal taste, personally I don’t like the style, further drawbacks for me would be the conservatory being open, if it’s anything like our previous home the conservatory was absolutely freezing in winter, so it maybe difficult to heat the room, in summer we had the opposite issue.
I would check if there are any planning apps on the surrounding fields, and also any public footpath issues.
The garden steps would bother me, especially with little ones or elderly relatives, the garden seems small. What does the front of the property look like? When you view consider, the layout and if that works for you.
With regards to price and what you should offer, assuming you like it when you view, offer what it is worth to you, bear in mind that often a first offer is rejected. But if it’s a buyers market, worth a try.
Good luck.
