Booked though Viator, I had a private tour with Raffi (guide) and Avet (driver) from Hyur Service in Armenia. It was a very full day trip to 3 monasteries/church complexes of Khor Virap, Noravank and Tatev monastery and ropeway, plus a lot of wonderful scenery along the way. Raffi was incredibly knowledgeable, extremely engaging, and professional - a top-notch tour guide mixing the right amount of knowledge, topics, and free time to take pictures. It was a fantastic experience, and I could not recommend Raffi, Avet and Hyur more.
