Our tour guide, Hanno was very knowledgeable and he told us about the history and stories behind the all places we visited. He also very patiently answered all our questions about everything, from life under the soviet rule to Estonian customs. The tour was very well organised and all the places we visited were expecting us, and the 4 hours flew by. I can highly recommend this tour with Estonian Experience and Eva-Maria.
