We took this tour when we first arrived in Rome and are very happy we did, The guide was very informative and if you are a first timer in Rome it gives you a good understanding of how the city is laid out., allowing you to get around much easier on your own.
Another big plus is the hotel pick up. Especially if you have travelled a long distance to get to Italy the day before. There was a comfort in knowing I did not have to find the meeting point, early in the morning, in a city I did not know well.
The fountains and squares have so much history and the guide made them come alive.
