Wanted to give credit to our guide, Lucy, who did a great job! We arrived late due to issues with a bad Uber driver who was late and dropped us on the other side of the Tower Bridge. Lucy communicated with us by text to make sure we could easily find her once we arrived. Then, despite the late start, should took extra time with us to make sure we received the full tour, despite going over our allotted time. She was very knowledgeable and really made the tour "come to life." Highly recommend Lucy!
