We choose to do the bike tour on our last day (we had booked for the day before but it was raining so we changed dates - which was no problem- great!). Tanja out guide was great - she is dutch and it was great to hear her explanations in dutch for our youngest daughter! The tour was really interesting - we saw the highlights like the houses of parliament and buckingham palace but also funky places that you normally would not get to like the grafitti tunnel. Thanks for making our last day really special Tanja!!
