OP, before you reduce the price / spend loads on decorating I would get your EA to do their job.
It looks like a nice house!
But:
The pictures are dreadful. Taken from weird angles, making the ceilings look low, and the kitchen look dark and as if it was on a submarine or something. Plus there really must be a garden pic
And obviously, the floor plan.
Also the EA name and contact are not clear on the listing.
Is there a reason for Zoopla and not Rightmove?
It sounds as if you have had a terrible time, and I hope you get a good and fair price to support your future. Don’t let your EA get away with this shoddy marketing!
