We were a group of 4 people visiting Iceland and we took several tours - the South Coast, Golden Circle, Silfra, Snæfellsnes, and the Blue Lagoon. Zeynep built our itinerary and gave us very clear instructions on the time and place to be for these tours. I will even give her credit for arranging for the terrific weather. When our return flight got changed, Zeynep was right on top of it and updated our return trip to the airport. Thorough, organized, and friendly! We were more than happy with the excellent service Zeynep provided and very grateful for her plans that allowed us to have a first rate visit. Thank you very much!
