Thanks everyone. We're not certain where we'll be living, but it's looking most likely that we'll be in my husband's company flat near Victoria Station.
I didn't really specify a particular area because I'm not going to be working, so I'm looking forward to exploring lots of different parts of the city. I love finding hole-in-the-wall restaurants, great markets and little shops (not chainy things that we have here, like the Gap or Starbucks).
