I discovered Calleo when I arrived in Krakow for working few months for my company. I started particular classes during the summer, because I wanted to learn as quick as possible, even if I realized quite quickly that learning polish could not be really quick. Nevermind, I enjoyed my lesson so much, that it was like a break after a hard day at work! Also, it has been a great opportunity to meet other foreigners learning polish at Calleo during some visits or parties organized by Calleo. After 9 months, when I left Poland, I was able to speak with my polish collegues and friends in their language, and when I came back for holidays in Krakow few weeks ago, I was impressed to see that I still could understand and speak polish with them! Bardzo dziekuje Calleo!!
