This was a great tour with a very knowledgable and very passionate tour guide whilst also keeping it humorous. The heavens opened on the day but it didn't dampen what was a great little excursion. The behind the scenes talks about the fountain and the waterworks in general were amazing.

Valeria was wonderful and knowledgeable. The acoustics were the best we have experienced with the earphones. We enjoyed seeing the aqueduct and the Trevi fountain but we wish we could have gotten closer. Excellent tour.

The tour guide was wonderful and we saw the underground of the water table which is a different perspective of the Trevi Fountain.

Amazing Tour Guide Federica

Pierson_S, Apr 2026

First off, if possible request tour guide “Federica Marrore.” She is beyond amazing, her commentary and communication skills were outstanding. When she shared her knowledge of this tour you could feel her deep conviction of love for her country. My partner and I who share a total of 70 plus years experience as flight attendants was very impressed with how she made you feel more like family and not just tourists. We will for sure be recommending this tour be a “MUST DO” when visiting your beautiful country. Thank you Federica you are such a blessing.

Response from Host, May 2026

Thank you so much for taking the time to write such beautiful words! 🧡 We're so happy you enjoyed the tour with Federica and we hope to see you soon again next time you're in Rome! 😊

Trevi Fountain underground tour

Mark_G, Apr 2026

If you are interested in the history of Ancient Rome, this is a great tour. It’s only 2 hours but you get a lot of information, and get to see places most tourists don’t.

Trevi fountain/underground

Anonymous, Apr 2026

Was somewhat difficult finding the tour guide. We w stood at the address for 15 minutes. No one came to get us. So one gentleman went looking around, and he found our tour guide in another place. Tourist came and told us where we should go.

Exceptional tour with Sabrina - well worth doing

Michael_B, Sep 2025

We were recommended to take this tour and so glad we did. Our guide Sabrina was excellent and so knowledgeable and helpful. Really passionate about Rome - definitely recommend. We started at the Spanish steps and needed up at the Trevi fountain. Well worth taking a tour if you love history. Sabrina was a lot of fun and kept us all interested - a small group from around the world - very fluent in English as well to make it very easy to understand. 5 stars

Not my favorite tour

Sandra_S, Sep 2025

The tour moved very slowly and you stood around a lot while they just spoke, which wasn’t too exciting. While there was some interesting sites to see it wasn’t my favorite tour.

Response from Host, Sep 2025

Hello Sandra, Thank you for your feedback. We’re sorry the tour felt slow to you. Usually guests enjoy the balance of stories and sightseeing, as the tour covers over 8 points of interest in 2 hours. We appreciate your comments and will keep them in mind as we continue improving.

The location and...

Janice_M, Aug 2025

The location and activities were excellent. Very well organized. The only negative was the tour guide while very nice and seemed knowledgeable her accent so heavy we could not understand much of what she was trying to impart.

Enjoyable Tour

Antonio_F, Jul 2025

Ricardo was very informative of everything. He made jokes and explained things well. We enjoyed our tour.

Aqueducts of Rome - just brilliant

David_C, Jun 2025

Sabrina was a superb guide. Such an interesting tour covering the history of the Spanish Steps, the Trevi fountain, but most importantly, the history of Rome - the levels of the city over the centuries, the aqueducts that supplied Rome with water from afar. A great history lesson, please do this tour if you want to learn about the old world Rome, it’s brilliant.

Trevi underground

Barbara_C, Oct 2024

Going underground to see how far down the water was. I wished we could’ve seen more of the underground areas. We had a wonderful tour guide. It was very informative and interesting. Interesting to spend time with.

AMAZING!!

Hannah_L, Jul 2024

This was a fantastic tour! Federica was incredibly knowledgeable, and shared many things with us about Rome and the sites that we saw. I booked this tour because I wanted to see the Vicus Caprarius, and this was an incredible way to see that site with a tour guide who brought the city to life, and showed us some hidden gems along the way. We had a wonderful time! I went with my mother and my brother, and the tour was the perfect length of time, and good for all weather, since we were in and outside. We left the tour energized and wishing we had time for more tours with Live Virtual Tours! I cannot recommend highly enough!
