Contrary to some other comments, I don't think the kerb appeal and astroturf are dealbreakers. They are easy enough to fix. I can see why you did the astroturf (my sister did it for the same reason) but your pets will have peed all over it and that's a bit minging with plastic.
Personally, I'd ditch the sitting area in the kitchen / diner. It's not needed as you have a lovely sitting room (I'd probably get the EA to re-label the photo to 'living room' or 'sitting room' rather than lounge). Then you could shift the dining table nearer the patio doors (nice aspect out on to enclosed garden whilst eating) and move the fridge freezer against the wall where you have the coats and shoes. The fridge freezer is a massive eyesore so I 100% think you need to solve that somehow.
Re decluttering. I think the process goes - declutter, and then when you think you've decluttered, declutter again. I speak from recent experience. If it's not essential to your daily lives over the next 6-12 months it needs to be gone even if it's into storage.
I love the colours and think the floors and doors are good. I'd want to see storage though. Where are the wardrobes? Where are the cupboards? In bedroom 1, that curtain thing at the bottom of the bed is weird. You need to go simple as it's a small room. Get rid of that suspended shelf - it's just clutter and serves no real purpose. I want to see more angles on the bedrooms. I want to see the shower so I know there is one and it's not knackered. The bath is fine - not very trendy but it looks clean so can be replaced in time. In the study, get a simple smaller desk - will the room fit a futon? That way, it looks like you can have a guest to stay. What's in that space next to the downstairs loo? Is it storage?
I don't know the area at all so can't comment on the price, but I wonder whether it might suit downsizers? It's small to maintain with neighbours around and amenities close. The sort of thing I can imagine my mother moving into if I can persuade her to downsize!
I did also wonder what the hallway looks like. It's the first impression you get when you open the door and if you are getting viewings and it looks like you are, are viewers put off when they open the front door and see a dark hallway and just a set of stairs directly ahead? It looks like there's no natural light.
Finally, I'd be tempted to relist with another agent. I think the photos don't do the place justice and the copy is terrible. Opening with the words, 'extended to the rear' for a start. The house is clearly small so it's advertising the fact that the original footprint was even smaller and any additional space has already been eaten into. The 'open plan social space' onto the garden is a small dining table and a sofa - not exactly a fabulous entertaining space (although it could be). 'The house briefly comprises' - pointless sentence as you can tell what rooms it has from the floorplan. Also, the repetition of 'three well sized bedrooms' in the first paragraph is just shoddy writing, especially given they are not that well-sized. Did we already say it had a garage and a 'private rear garden'? Well yes, I think we did, two sentences ago. Second paragraph, ditch the word 'development' - sounds functional and 'neighbourhood' would be better. The house is a mile from Warwick train station - that's seems like a great selling point to me so should be made more of. Ditto, the M&S, Co-Op, pub and countryside. Location sounds pretty ideal so they need to shout about it.
The more I read the copy, the more I want to shoot the person who wrote it. It's lazy. You have a lovely house. It needs someone to earn their money by marketing it appropriately for the right type of buyer. Once you've done all that, you may need to consider dropping the price, but I'd get a couple more agents in after Christmas to get a second opinion.
