I'd make another vote for Marlborough and surrounding area. We live in a village North of Marlborough 10 miles from M'borough, 10 Miles from Hungerford, 8 miles from Swindon.
Its a lovely area with all kinds of amenieties available form the towns and our village as a strong community and lots going on all year round but especially in the summer its a great place to live with a family. And most importantly we have three craking pubs and a lovely resteraunt in our village, the best thing in the summer is to go down to the pub on the village green, let the kids play together and enjoy a relaxing drink, heaven!
We also have a great local nursery in our village which also has branches in other local villages in gorgeous converted barns and very good state local schools as well as a good range of private schools if thats what you want.
Wiltshire is lovely anyway with the downs, the ridgeway, lots of lovely walks around there and world heritage areas like Avebury, The white Hourses etc.
I work in London part time and commute from either Hungerford /Great Bedwyn or Swindon. Its just over an hour.
If your intereted in a village heres a few lovely ones I could recommend, some of which have their own websites if that helps.
