Olly is the greatest tour guide
I highly highly recommend doing this tour if you are in London and looking to capture the sights. You go thru so many landmarks and it's worth. I recommend going on MWF or Sunday so you can see the changing of the guard march. Olly was awesome and he was always lively. He kept the tour engaging and played awesome music when we were riding our bikes. A HUGE plus is that the tour provides ponchos if needed for when it rains.
