Highly recommend Black Taxi Tour . We were so lucky to have Rachel Martin-Peer as our amazing tour guide/driver. She was so knowledgeable about everything London and knew exactly what my family wanted to see and not see. She totally maximized our two touring days in London. My whole family loved her. Traveled with my 20 and 18 year old girls and she knew exactly where they would want to go and get great photo ops. We highly recommend Rachel Martin -Peer. She truly made our short visit spectacular. She is a must have as a tour guide for London. Can’t wait to go back.
