Far cotton isn’t too far from Northampton train Station, its closer to town centre. If you moved to Wootton you would pass through far cotton to gain access to the train station anyhow.
You could even get a bike and cycle to the station from Far cotton if you wanted to save on petrol and parking charges.
Far cotton has some nice, and some bad areas. Delapre is even closer backs onto far cotton and that has some nice houses as well, but again you need to pick your spots. Its more affordable then Wootton and has a nice park (daytime, bit iffy at night) and its easy access to the train station.
You can easily walk to the train station from Delapre, about 30 mins, average.
Northampton town centre isn’t crap, its just basic. It has all you need, Northampton is so close to Milton Keynes anyhow, so if you want night life and shopping, then MK is just up the road, so to speak.
Seeing as you need to get to the train station each morning, then Wootton, Grange Park, Hunsbury, Far Cotton and Delapre are your best options.
For the love of all things, please do not go anywhere near the train station, such as Grafton street. Its very rough, worse then the Easton district.
Oh parts of knigsthorpe is nice, but that’s on the other side of town, and its known for very bad traffic in the morning, it would be a nightmare to get to the station each day.
