Un free tour IMPRESCINDIBLE y muy interesante sobre la historia de Oporto, fue ameno y divertido con Maria, guía local, y que valoro mucho de cara a conocer la historia de una ciudad.

It was a very interesting tour. We learned a lot. He also showed us some restaurants to try.

The walking tour with Shab was wonderful! He shared many interesting stories about Barcelona and showed us places that aren't so popular but are still significant and well-known. His English is excellent, and he kept a very positive mood throughout. My children and I thoroughly enjoyed every part of the walk.

Enjoyed the walking tour and the delightful information, stories and anecdotes provided. Liked that we started "on top" and progressively walked down to the river area. A minor point: we were with our 87 y.o. Dad, who also enjoyed, but was a little slower than the rest of the group. Appreciated the patience, but do note there are spots where he had some difficulty.

We were the only 2, so it was a private tour. Great walk and the mirador on the 22flour really surprised us. Unfortunately after the tour ended all the shops and cages in old market square were closed - wish we could spend more time there

Rafaela has a really cool style of explaining São Paulo's history, with many fun facts to share. We really liked getting to know the city center with her and the group, and also to hear her personal anecdotes about the city. Super recommended and big thanks!

Antonio was a very knowledable and kind guide who shared with us many interesting facts about Aveiro. We enjoyed the tour and Aveiro and recommend it as a great introduction to the city!

Dashel gave us an entertaining and informative insight into Sorrento. Being a local, he was able to explain in detail, Sorrento culture, food, arts and crafts, plus history of Sorrento. Dashel is approchable and made the tour fun and interesting.
