The tour was really nice and good organised and lead us over the old town in Dusseldorf. only one question was hard to solve because the solution was on a covered building because of re-constructions. So we had to check street view from Google to see the building and solve the question. But in over all, everything was perfect and really recommended. Big thanks for your effort in organising this activity.
