Conventional wisdom says that if you're not getting viewers in the first place, then you need to look carefully at the asking price. Are you sure it's priced right for the area?
You could do with better photos -- a lot of them look very dark. Just tweaking the exposure would make a big difference. And some of them are from odd angles.
It does look a bit clinical and unlived in. Looking at last year's photos, yes, you decluttered WAY too much.
The kitchen looks quite small. And the bathroom is TINY (based on the floorplan).
The back garden is offputting. If it's paved all over, could you put in some plants in pots to soften it up a bit?
Description is sketchy.
It's leasehold (that alone would put me off - for RCheshire, because I've spent the last twenty years living in leasehold flats and if I'm going to buy a house and so finally be able to buy freehold I'm not going for another leasehold property) but no details given on length of lease remaining.
I wouldn't view it because (a) the bathroom is so small, (b) the kitchen is pretty small, and (c) the garden looks like it will need a lot of work to turn it from a yard into an actual garden (again, I've spent the last twenty years living in flats with no garden, just a balcony or roof terrace if I'm lucky -- if I'm buying a house with garden, I want actual soil
). I could probably live with (b) and (c) if other stuff was right, but (a) would make me strike it off the list without viewing (and, unfortunately, there's not much you can do about that).
