once I had 10 hours layover in London and I took 1 day pass for the underground from the airport and it took me everywhere. and it was fun and adventure.

I also recommend the double deck bus for sightseeing.

I've heard that the London eye is great and Hyde Park. and what SamyaUK suggested.

I've heard is sooo cold there so take worm cloths.
