Chinese class recommendations

How bad is NTNU? I’ve been looking at all these threads and you seem to have a crusade against NTNU.
Here’s my situation:

  1. 0 Chinese knowledge. Thank you, hi, excuse me. That’s it.
  2. I live near NTNU, 5 minute bike ride.
  3. I have flexible work hours, so I can take either early morning/late night classes.
  4. I have a limited budget, NTNU’s regular group class at around 25000 NTD is my cap.
  5. No real drive to learn. Girlfriend and friends all speak English. Office uses English when it comes to work related stuff.

My girlfriend (local) was quick in suggesting NTNU when I told her I wanted to take Chinese classes.
The only reason why I want to take classes is because I feel like a douchebag running around Taiwan expecting people to be able to understand me.
