My wife and I enjoyed three full days of touring under the guidance of Rachel Martin-Peer. There are not enough adjectives to describe her extraordinary knowledge of British history and royalty or her kindness and special attention to our questions and desires throughout all of our days with her. Once we had booked, she began communicating with us and making arrangements to ensure we saw everything we wanted. During our stay in London, even on her days off, she communicated with us to see if there were any ways she could provide additional help during our stay. I don't believe there is a better guide in London and we would give our absolutely highest recommendation to anyone who is looking for the best possible London experience!!
