Our driver's name is David, and it was a great experience from start to finish. He picked us up promptly at our hotel - Brown's, which is not on the "pickup at hotel" list but was no problem at all after our concierge called - and proceeded to give an outstanding overview of primary sights of London. This is exactly what we were looking for since it was my wife's first visit. History and fun in each area of central London, delivered with a lot of charm and wit. Not inexpensive but highly recommended by us. Helped us understand exactly where we wanted to revisit during the rest of our stay.
