We were so lucky with this tour. There were four of us and just the four of us on the tour. Perfect. Our guide was lovely and gave us a whistle stop tour of Rome, stopping at all of the prime tourist spots and allowing us enough time to take a quick look and take a few photos. She gave us lots of information about the various historical sites. We were so lucky with the weather too, it was forecast rain with thunder and lightning, but we only had a 15minute quick shower. I can't quite imagine that we would have enjoyed it as much if it had rained the whole time. We would usually tend to do a walking tour, but I have a problem with my foot at the moment which meant that I wanted to try and limit the amount of walking I was going to do over the course of the few days we had in Rome, so the bike tour was a perfect solution and ticked all the boxes. Any tour like this, gives you a start on getting your bearings with where everything is and can even give you more ideas on places you might not have originally considered seeing and also on spotting bars and restaurants to try out. Not sure how well it would work when it is high season, with more pedestrians and cars to deal with. But for us it was definitely well worth it.
