Our tour was awesome! Belen was very thorough when describing the culture, history, and uniqueness of CDMX. She shared some of her favorite spots in the city, and we probably wouldn’t have found those hidden gems along the tour without her. Will definitely recommend! 10/10

This is a fabulous introduction to Shanghai and a fascinating history, it's a 'must do'. The time goes quickly and lots of distance is covered....it's hugely engaging and great to be amongst the company of fellow travellers.

Interesting and well-organized introduction to Sintra with a friendly guide. Enjoyed hearing stories about his childhood there and how the town has been affected by tourism.

Tour muy completo. Enseñan las principales zonas de la ciudad de forma muy profesional y amena. Repetiría sin duda.

Very informative and entertaining tour. We learned a lot about the history of the city and got to see many places we would not have discovered on our own. In addition to history, the guide also discussed more modern Croatian history and life.

Súper interesante, dinámico y el tiempo vuela con estos tours! Vuelvo a Barcelona y lo vuelvo a tomar!

Muy entretenido y agradable. Recomendable 100 %

A good way to see some of the highlights of Skopje if your time is limited.
