I'm going to book a flight from Amsterdam to London and I can choose
between
the airports Gatwick, Luton and Stansted.

Does anybody know from which airport I can get the cheapest transfer (by
train) to the center of London (Piccadilly Circus)?

Cheapest, but probably slowest and leats comfortable, is the Picadilly line
to central London.
