Beautiful, busy, expensive
People here are constantly rushing. This is a beautiful place full of history and national pride. But please, never stand in front of busy londoners at the tubes, trying to figure out your turist map - they are alwasy in a hurry. One of the best public transportation systems in the world, take your time on the double-decked buses to look around the city. I'd recommend line 24 (runs around most of the turistic sites). PLEASE visit the British Museum. It was my favorite of all time.
Insider Tip:Get an Oyster card as soon as you land. It's valid on most forms of public transportation, and it will be cheaper to purchase a travelpass for the duration of your stay. Look up details on tfl.uk. And.... be prepared to spend lots here. It is an extremely expensive city (and queen's money isn't cheap)
