Some impressions from the classes/rooms in different locations

Germany location:
There is a huge room and several smaller rooms
The smaller rooms are sometimes favored by the students because it is even more quiet and comfortable.
However you can change the rooms any time. There is lots of space for your laptop, books and folders.
The rooms are flooded with natural light and fresh air.  You can dim every light to your convenience.
There are glass walls between the rooms and the instructor's office. You won't hear any router noise !
