A must way to see Sao Paulo: Denis was truly fantastic, both in terms of accommodating our interests, and also impressivley knowledgeable and an etremely friendly individual -- qualities which are fantastic when combined into a single individual. I am so glad we chose this trip (myself and a work colleague/friend). We only had one day to see the city, and chose thi 8-hour tour (which in fact even lasted slightly longer in the end). Denis could advise on main things to see, was very safety cautious, and managed to find a parking spot directly next to every place we visited. He clearly does that regularly and knows people in all the visited locations: but, while he makes fantastic recommendations, the choice of what to do in the itinerary is truly yours, giving it an extremely personalized feel. Without this tour, we would not have seen even half the places we visited, but even if we went on our own, we would not have known all the historical and fun facts we learnt on the day. Same company does other tours, and I would recommend them most strongly! Personally, I feel Sao Paulo is a rather "chaotic" city for a tourist, and such a tour took all the stress away and let us really enjoy all the wonederful things the city has to offer ... and feeling 100% safe all along, even if going to places I would not have gone on my own.
