Risposta di Your best Dutch Guide:
Thanks for the comment Issar! Our current route is made for the winter time. At this time of the year it’s cold and rainy, so not everyone can walk 2-2.30h (duration of our summer tour). That’s why, this routе is constructed in a way to get the most of the city in a suitable for this weather time limit. Also, we are mentioning the duration of our tour and all the stops in the description, so before choosing everyone can decide if the route and time suits them.
Despite that, we always provide additional guidance on more points before, during and after the tour :)
