Eww. Sorry but it looks grim and depressing. serin said streetview was nice - and it is actually very nice - but that house looks like it belongs in one of those grubby streets of identical miserable houses that look as though they are full of miserable people living grim lives (I'm thinking driving through Acton on the A40).
Cheap/free improvements
Garden: clean the slabs, shed and wall. Put a chairs & the table along the side of the shed and make it look like it would be nice in summer.
Floor plan: needs one.
Photos: have a photo of the lovely road too.
Living room: It's all been said: dark & dreary. Rearrange the furniture, brighten it up, take photo on a better angle with as much sun coming in as you can.
Kitchen: get more light in. Consider painting units white (kitchen unit paint is cheap and makes a big difference).
Bedroom: is that the nicest bedroom? If not, get a lovely photo of master, which is really big according to the blurb. It's fine as a 2nd.
Bathroom: at shower curtain and the towel. Dress it nicely, and make it look really, really clean.
Lean-to & cellar: this could be extra living space or extra storage. Either way, a photo would help to visualise potential if not actual use.
