Merged: Price for individual teacher in Polish

I will be staying in a smaller town in Poland for a period of two months in the fall of 2015. During the stay I would like to have private lessons in Polish. In the town there is only 1 supplier and the price pr. hour is 15 euro.

I am not familiar with prices related to individual teaching of Polish. My question is whether this is cheap, expensive or acceptable. It is a language school that offer this service so I must assume that their qualifications are superior. In advance, thank you so much for your feedback!
