Perfect tour, we all loved it. First of all - the group is small, and as I understood they are kept small intentionally. Everybody was able to talk to Pedro directly during the tour and ask questions, so it was truly more like a friendly walk, not just a rush through all the places of interest. Then, as the group was small and he didn't use a speaker, we were able to enter churches to explore them from inside, which is very unusual and rare for such tours. Pedro even waited in queue with us to enter Pantheon. Broad knowledge of history and architecture were also impressive - we loved his explanations and description of different pieces of art that we came across during the tour. Overall, this tour was certainly one of the most positive impressions from our stay in Rome.
