Alessia is great! - We had the Trevi District Underground guided tour with Alessia yesterday. She is a very knowledgeable guide who not only explains everything in great detail but also gives you extra tips for other city’s historical places to visit. Overall, we were very satisfied with this tour and would consider other tours with this provider.

Fascinating glimpse into the history of Rome and the water system feeding Trevi Fountain - amongst other fountains. - Very interesting tour of the underground water system, lovely guide, definitely recommend. The “Layers” of Rome and corresponding periods of time are mind blowing!

A different perspective. - This is not a trip under the Trevi fountain but a look at the history of the aqueduct system in the Trevi area and Rome as a whole. Erica was our guide and she was very friendly and knowledgeable which made this a great experience.

Good, but not what we expected - This tour was very interesting but my group did expect something bigger, so be aware that this tour is not long or very big. This is a tour of a small area under a building. The information was very interesting and the artifacts were really cool. We just expected more and I think from the look on some other peoples faces, so did they, so just be aware that this is a small area. Our guide was great and the fountain was beautiful. The tour does not include the guide at the Trevi Fountain, it just includes the cost to go and take your picture in front of it.

Enjoyable Tour - This is worth doing but you should definitely book these tickets in advance, tourists were turning up on the day wanting to buy tickets, long lines (there is too much to see in Rome to be wasting time in lines) with the possibility of missing out. The meeting point was easy to find (not far from Trevi Fountain). Overall a great tour and very informative.
