Honestly OP, I think it’s fine, and the price is okay.
What I would do is major declutter, make the conservatory a conservatory and not a storage room. Minimalise wherever you can. Viewers should be able too see beyond clutter, but many can’t. Could family, friends store stuff for you?
I think it’s a perfect retirement bungalow, in a nice area.
So I’d put baby plans on hold until next Spring, do the declutter, and hold firm on the price. If no sensible offer before then, give the estate agent notice, have a break, then remarket just before Easter with new agent . I think prices will level out, maybe increase next year, so hold tight for now.
