Without a shadow of a doubt, West Byfleet. Very nice area, secluded spot next to numerous golf courses. Commute is one of the nicest and trains frequent and journey quick. During rush hour the time from door to desk is about 55 mins, which includes a pleasant walk across w'loo bridge. It's in an affluent area so no trouble with crime.
The only trouble is, as someone has already mentioned, you will prob go on a waiting list as it's very popular esp with Army wallahs. Most on 2/3rd tours and when I was there the record was over 10 years in situ!
Schools are excellent (local junior school has just had an "outstanding" OFSTED report.
Best patch we've been on and comes highly recommended from me!
