Hi, I'm coming to Buenos Aires next month to learn Spanish for 4 or 5 weeks, want to do an intensive 20 or 30 hour a week course and also looking for a school with a good location and good social scene so it's easy to meet people. But also want the teaching to be high-quality and to be taken seriously. I've so far narrowed it down to Expanish or Vamos, I can't decide which one! Can anyone recommend one over the other? Thanks!
