We had a long layover at Heathrow and did not want to waste 12 hours in London doing nothing, so we booked Black Taxi Tour to show our teen girls around the highlights of London. It was fabulous! Within an hour of landing we were rolling into London with Keith as our chauffeur and guide. He took us to all of the iconic places in London, found us a great place to have lunch, showed us some behind-the-scenes Harry Potter bits, and returned us to the airport in time for our connecting flight. It was the best layover we’ve ever experienced! We will book again the next time we find ourselves in London. Highly recommend!
