I attended Toucan Spanish School for approximately 4 months. I started with a basic working vocabulary from taking high school Spanish, but, beyond that, I didn't have any real speaking ability. The management is super flexible- you are able to pay for a certain number of hours and, say, you want to skip a few days to go on an impromptu trip, you can; they will just credit your payment for further classes.
I started with group classes, which I recommend for beginners. I was able to make many friends from different countries, and I learned basic conjugation, past tenses, future tense, Colombian phrases, and was able to describe things I did, people I knew, etc. For the beginner classes, I had Sara as a teacher. She is great at letting you speak and figure out things on your own, while still being able to explain why we would do things a certain way. Everyone who has Sara as a teacher knows how much she excites students to learn.
I also took individual classes with Sara, and did smaller group classes with Laura. We worked on listening skills, story writing, everyday conversations, etc. Laura has traveled the whole country and has an infectious energy, plus her experience really shows when she is explaining difficult topics.
I would say I did roughly 220 hours of lessons, bringing me from an A1 level to a high A2/low B1 level, based on the CEFR framework. Now, I will continue my learning stateside, using Duolingo, music, television, and speaking with native speakers in Florida. The great thing about Toucan is they also offer online classes, so I could potentially keep going with the classes even when I am not in Colombia.
