Looking for a good Spanish class (Prague)

Hello,

I would like to start learning Spanish, so I am looking for a Spanish class in Prague, starting from September.

It would be great if someone can recommend me a good language school with a good Spanish teacher. As I have learnt some Spanish before, I would like to attend a class which would go through the basics again but in a faster pace.

Any recommendations would be much appreciated.
Many thanks,
Alena
