Translation of enjoyable in Spanish

I will be visiting in Italy from April 10 to 15 in order to meet some old friends. I'd like you to attend a one-day course, maybe I can help you in learning something new. Please give it a try.
I have always met nice people so far, and I have never had a strange friends request. So far I only had problems with my grammar in various foreign languages that I am trying to acquire.
The course was a bit tough because the teacher always gave lots of homework. We were upset about his behaviour. He was very arrogant towards all the students. It was simply no fun to study there.
