we were a few friends traveling together and our schedule kept changing. Zvika was very accomodating with our itinerary. He was friendly, very knowledgeable about a range of topics - history, architecture, nature, etc. and was very happy to advise us for parts of our trip where we weren't using him. My friend had booked different guides for Jerusalem, Jericho and Bethlehem and we wish we had used Zvika for the entire trip.
