Costa Rica is a wonderful country, so you're lucky to have a family there. I visit Spanish-speaking countries pretty often because their culture attracts me. And with Duolingo, I managed to learn the basics of this language. But now I'm thinking about moving to Argentina, so I have to prepare for that and reach a decent level in Spanish. I'm thinking about classes from https://preply.com/en/blog/best-online-spanish-classes/, and I hope one of them will be effective for me.
