If you're serious about learning the Russian language, Privet school of Russian is an excellent choice. From the instructors, to the location, to the style of teaching, it will be difficult to find an opportunity to learn Russian faster and more effectively. Additionally, they make it very comfortable and simple to arrive in Russia. Having never been to Kaliningrad, I was nervous about simple things like getting to/from the airport and how to handle the VISA process...etc. Privet school picked me up and dropped me off from the airport and guided me through the entire VISA process. Therefore, there was nothing to worry about... I was just focused on learning Russian.
