Hi @BorrisS
Thanks for your attention. Indeed it was my first time visit there. What I enjoyed the most? The hospitality of local people. And almost freedom for traveling, means very secure day and night, all public open spaces (Kazan Kremlin territory, as an example) are open 24 hours. I liked local cuisine, as well. And architecture, both modern and antique are really beautiful.
By the way, it’s not too expensive place for traveling. Tatarstan is a part of Russian federation, so is not necessary to make a different visa for visiting. It’s just less than a 1.5 hours flight from Moscow, cost me just a 50€ for two ways ticket (it’s low-cost Pobeda airline). Accommodation is quite cheap as well. Hostel prices starts from 10€ and up. Airbnb prices starts from approximately 20€.
