The fastest way to get from Heathrow* into the city is by train (15 minutes to Paddington Station).
Of course, we then took the Underground (London’s name for its subway system) to the hotel. Unfortunately, I got a bit lost and had to hop into a one of these to actually find the hotel.
London’s Underground is famous and a bit of a tourist attraction in its own right. London limits where cars can go, so it is also the fastest way to get around the city.
This is the gap. We minded it.
One evening, we took a boat ride down the Thames. It was a great way to see the city and on the London Transport Boat, which was surprisingly cheap.
Just about the only public transport we missed riding was one of these red double-decker busses.
*I like Swiss Airlines (especially when it is cheaper than EasyJet) because they always give you free chocolate.
