I will admit I booked my tour to Noravank and Tatev with One Way Tours simply because they were so cheap, so to be honest I didn't expect it to be perfect. But it was! I really liked this tour, even though it's a very long day with lot's of time in the car. The van is really comfortable, the driver was responsible, and our guide was so lovely! She did a great job explaining the monasteries and facts to us in Armenian, Russian and perfect English, and she was very kind and caring, too. We had a small group which was comfortable. There is only one stop for food and it's very short and basic (but also very budget friendly) so I do recommend you take some snacks or at least water with you in the car.
I hope to take another tour with this company shortly because I enjoyed it so much. I like to go to places by myself by public transport normally, but for this price I couldn't have done it myself or it would have taken a lot of time and hassle so I find it really good value!
