London has everything you could want,some of the best cuisine in the world,arts,sport,fashion,music the list goes on and on.It's also probably the most multi cultural city in the world,which might not be your bag.I've lived in London my whole life.Personally I would never live in central London,but there are many very nice quiet suburbs a 15 OR 20 min tube ride to central london.Yes it has some shit areas,but so does every big city.
