Hi Edouard, Hang on to those euros! They hit record highs against the dollar every day and it just keeps on going. San Diego is tough, I don't think there is any one place that has all the things you are looking for. I live in Sorrento Valley but there is nothing to do there and nothing to eat. So I go to Clairemont or Hillcrest to eat but I wouldn't want to live in either of those places. When I want something to do I go to the beach or downtown or La Jolla, none of which are very close to where I live.
Why do you need a 3000sf house? Didn't you get used to small living in Paris? Check out this house, for me it's huge and it has a huge lot right on a canyon in a nice neighborhood close to UTC (near where I live):
