We loved it
We did a private tour in november. It was perfect. Our (Dutch) tourguide Elmer was very nice and told us a lot about London and its secrets. Traveling throughout the city by bike is so different from other forms of transport. You see so much more.
We stopped at our request at Covent Garden for a quick break together with Elmer which was really nice. He took al the time for us and he gave us a lot of tips for the rest of our stay.
We really recommend booking a tour here and heen you are Dutch, Ask for Elmer!
