What kind of "tips"? When I moved here I got rid of my car as I hardly ever used it. Are you going to be renting a place or buying? If you are thinking of buying, my place is up for sale.
No seriously, if you are, I would advise you to rent first so you know whether you like the area at all. All areas of London have good and bad parts. It depends on which part you are thinking of moving to.
