Tour would have been great but having a set day to do it on we had no choice but to do it when it was pouring with rain. we did try to stay on the open top but a couple of minutes into the tour we had to move downstairs the rain was so heavy. only seats available were at the back of the bus where we couldn't see anything. There are not many seats downstairs about a dozen! Bus did stop for people to get off to take photos of amazing view but weather so bad no-one did. Tour would be great but only on a day you can sit up top.
We have done this trip before with Viator so of course when we returned to Rome it was Viator we came to again. We enjoyed the trip as we had done on our previous visit. Only this time on the Sunday the bus took a different route as what we found out later was because of a Carnival. All we had got told on the bus was it was a different route because of something happening in the center of the city. It would have been nice to have been told what was going on so that we could have went to see it!!!! Would have given 5 stars if we had been told about the Carnival.
