I've been living in West London for the last 3 years with my wife and 4 year old son. Prior to that I was living in Barcelona for 1 year and Amsterdam for 7 years before that. I love to travel, and have visited all the continents except the really cold ones! I own two properties, (one London, one Barcelona) which from time to time I make available (as the entire place) on airbnb. I've lived in both, so can give you good advice about what's nice to do/see/experience in the respective cities.
