Question: is bletchley a nice place to live?
Answer: Bletchley is good to be near (as PP said, lots of big shops, a range of supermarkets) but not great to live in. North of MK, Olney is lovely but pricey. My recommendation is the villages between Bletchley and Leighton Buzzard, where I live - the Brickhills, Stoke Hammond, Soulbury, Stewkley.
