We recently took a 4-hour tour with Frank and it was fantastic! It was our first trip to London, and we had a mix of things that we were hoping to see. He was able to show us all of it, plus a ton of other things. Not only was he able to quickly and accurately move around the city from place to place, he took tons of photos for us, and gave us the history of everything. My daughter is a big Harry Potter fan, so he made sure to show us some of the filming spots, which was a huge hit. This was definitely one of our favorite days in London, and we will definitely book another tour when we come back. I highly recommend booking a tour with them. Ask for Frank!
