Booked a 4 hour tour of London essentials driving tour. Richard is extremely professional and a wealth of knowledge. We requested to be picked up from the Eurostar train station as we were coming from Paris to see London for a few days. He picked us up in a clean Mercedes van. Drove all through out London with plenty of photo stops. Gave us tips for where to eat and what to do on the other days, even told us the best place to stand to watch the changing of the guards the next day. Definitely would use again.
