Owning your own home

My wife is less and less sure that we should be living in London. Where should we thinking about moving to which:

• Is in the south (not my choice)
  
• is near to a good city with things going on (Bristol, Oxford, London)
  
• has nice countryside around it
  
• is not too Tory
  
• has nice houses
  
• isn't too far from good road connections north.
  
  

Villages or small towns near Bristol seem to be leading contenders at the minute, but I don't really know any.
