My husband and I were in Astana just for a short time so we decided to visit the city with a guide, and Yerlan was the perfect one! he brought us around the old part and the new part of Astana, the Expo and the different religious buildings, explanining the history and many interesting things about Kazakhstan! He is very professional, knows everything about his city and his country and was always very funny! and as we are italian he could explain both in english and italian language.
Yerlan is definitely a great guide! :-)
