Our tour with Sergio was great. There were only 4 of us & this was still cheaper than any ships tour and we had personal service. We saw a side of Valparaiso we would never have seen without this tour and loved it. We also had a great lunch at a restaurant frequented only by locals. Sergio was knowledgeable, professional and considerate. We were most impressed when we became tired walking up and down those hills, so we sat and waited, while he went down, collected the car and picked us up. Thanks Sergio.
