It looks like a straight shot from the airport to Green Park Station via the Piccadilly line. Is that correct, or will I need to make a transfer? Thanks!
You are correct.
On most days......I only say that because much of the PIccadilly line wasn't running today due to a signal problem.
As the others have said, you are correct. When in London, we stay at a hotel by the Gloucester tube stop, and that's about a 40 minutes ride. You're stop is only a few minutes and 4 stops further. Pick up a tube map at the airport when you get on the tube. you can also download it the London transportation site.

Thank you! It looks so easy that even someone as dim as me should be able to manage it!
