As Suzan mentioned my husband gives Spanish lessons here in Cotacachi. He was a Spanish linguist in the Navy and focuses on conversational Spanish as opposed to the technicalities of the language. The idea is to get you speaking with the locals quickly. Most people take one or two classes per week and ideally the students practice what they’ve learned during the days in between. His rates are $10/per lesson (1 hour) for up to two people and $5 for each additional person with a limit of four people per class.
