First time we had a German/English speaking guide and it was amazing! ????
The tour was perfect to get a good overview of the city and its history. You should definitely do the tour at the beginning of your stay in Sucre because Lorenz will send you a personalised city map with all the highlights. Lorenz really took a lot of time to answer all our questions and introduce us to the culinary specialities of the region.
So, everything was great and can only be recommended!
