Hi there,I have been to Bellingua but just for a short time .I found it very good for someone who really want to learn quickly and intensively. Someone who need to do the test or need to study in higher lever for work or university. Because for me as an old lady I found with zero background in german ,it was pretty stressful and too intense but I would say the school is very good so just me thou
at the end I went to EB Zürich in Altstetten instead ,they are a bit more relax so i was not too scare&stress to go to school . ( also a bit cheaper same 3 hours from Monday to Friday for intensive course )
I also went to Alamenia but i think a bit too short for just for 2 hours per day.
Just a roughly idea for you so I hope it does help.
