I just compelted a 4 day tour with Sofi and it was a really great trip. She was quick to respond and very helpful to add advice to my proposed itinerary. To be honest it felt like I was traveling with a friend and not a guide. Her history knowledge is impecable and she is very well organized. She arranged a driver who i found to be very safe and reliable. I would highly recommend Sofi to any of my friends or blog followers who are visiting Armenia!
