Eduardo's tour was thoroughly enjoyable and educational, leaving me completely satisfied. I was slightly concerned about whether I could keep up for four hours, but it felt like it flew by, such was the richness of the experience. Alongside detailed explanations of the historical buildings, he shared insights not found in guidebooks. He paid attentive care to all participants (frequently pointing out where toilets were located, speaking in the shade, etc.), and spoke English at a very clear and audible pace, making it extremely comfortable. He answered any questions or queries we had with genuine care. Should any acquaintances visit Rio, I would strongly recommend joining his tour.
