Private classes, in group or for bussiness

I have been teaching Spanish specialized as a second language for more than 20 years.
I got a certificated from Instituto Cervantes and l am a professor in DELE examinatios.
The emphasis is based on coummunication, reading, short texts from literature or publicity in different topics, some songs, images, and other activities. Grammar it comes at the end of the classes, as a feedback, or if the student need it sooner. I work under the programs dictated by the MCER.
I really love to make a comfortable atmosphere in every class.
