The booking was easy, the pick up was on time. We chose the early tour at 4:30 AM so that we could avoid the heat and traffic jam. The driver was very nice. He drove safely and was informative. For the tour itself: the guide was funny but less informative than I expected. The group consisted of me and 2 of my friends. 2 tourists joined us later on. The hike up was a little bit hard but it worth it. I believe that it was a wise decision to book this guided tour than to do it alone.
