This classic bike ride through the center of London with Tanja is highly recommended! In 3 hours you see many high lights of London and Tanja knows all the stops to tell nice facts. She knows everything about unexpected questions too. Cycling on the other side of the road is not a problem either, Tanja goes first and makes sure everyone follows her. Nice was also a short stopover for a drink and chat with the group (or just walk around). Thanks again Tanja :)!
