Ideal EFL Classroom

I was wondering what your ideal EFL classroom looks like right now? If you were going to teach in a foreign country, what would the best set up look like in your eyes?

Some finer points in answering this question might be, but are not exclusive to:

• number of teachers in the classroom
• number of students
• number of hours with the class each week
• daily or weekly routine
• heterogeneous vs homogeneous student population
• technology

The above question is one I recently emailed to a very well known expert and researcher in the field of second language acquisition. I haven't heard back from him yet, but what was wondering what other people thought.

Please let me know in the comments any and all opinions on how an EFL classroom would be run if you could theoretically control the entire set up.
