I was the only customer, so it felt very special. My guide Filippo was very friendly and easy to talk to. I really enjoyed the tour.
The tour is well worth your time and is quite a tour - both in the amount and distance covered. Circus Maximus was the main goal for us, however, much more history was covered than we expected. We highly recommend this tour if you want to get a good cross-section of city life and history. If Italian is not your native language, do not worry - we went on an English tour and had zero issue understanding our guide.
