GT Tours, Mr. Guillermo Toloza; email@example.com; www.facebook.com/GTToursChile; +56-97-3067040. Guillermo operates a small/mid-sized 5 passenger car. Guillermo was an absolute delight, speaking excellent English (he’s conversant in 4 languages), and provided an excellent in depth introduction to both Valparaiso, and nearby Vina del Mar.
Part of the tour was walking, around and to the various sites of specific interest. He also drove us to some of the same sites as the tour buses (but giving us individual attention for about half as much cost).
When we stopped for coffee, and a toilet break, he did not charge us for the time, and extended the tour accordingly. We were so pleased with Guillermo, that we asked him for another hour, and to join us for lunch, and we went to a local restaurant in town (see accompanying photo of the appetizer).
All in all, I heartily recommend using Guillermo for tours or transportation services.
