The basement of the fountain - The tour was really interesting, the guide Andrea was very good. I recommend it to those who want to see beyond the trevi fountain. I recommend this agency "tix & tours" very professional and kind. Thanks Andrea for the tour and Thanks also to Elisa, for checking in fast.

Beautiful - A great experience! Andrea was a great guide: clear, passionate and full of little anecdotes that make the visit really lively. The welcome at the check-in with Hichem was equally impeccable, very warm and professional. The discovery of the Trevi Fountain was really fascinating. The pace of the visit was perfect, neither too fast nor too slow, with enough stops to take pictures and enjoy the place to the fullest. I recommend 100%!

Breathtaking - An incredible experience! The atmosphere around the Trevi Fountain is truly special, and seeing it in person is breathtaking. Our guide revealed a whole new world behind its history and details. One of the most iconic spots in Rome. I highly recommend visiting!

Trevi Gelato and history - I would recommend this tour to anyone who comes to see one of the most famous fountains in the world. Me and my girlfriend Sara were very excited to hear about the fountain story and what is hiding under it from our guide Andrea , she was very knowledgeable about it and she also suggested us a very good place for gelato after and some other directions we asked. Definitely will come back later this year i hope to get my parents to see and hear the story.
