I loved this program! I went to Buenos Aires, Argentina and stayed with my host mom in an apartment building across the hall from another host mom, and both were very friendly, happy, and easy to talk to (the food was also great).
Tips!
The Academia was really useful as a way to practice Spanish, but I recommend choosing a class that's somewhat challenging for you, or finding a class in which you get to talk a lot so that you get more out of the experience, either learning-wise or language-wise. My teacher was very engaging and the class was full of people who were having a lot of fun in the city and were very enthusiastic about learning and practicing Spanish, so I could overlook the fact that I was only doing review and not learning new topics, because I was gaining so much experience speaking.
Pack light, so that you can have some room for souvenirs like mate, which are surprisingly bulky!
Talk in Spanish to everyone you can, every chance you get. The students may not be immersive in the language and it is a great idea to practice the language as much as possible. I also watched movies and shows and read books in Spanish so that I could practice reading and listening.
Read ahead about fun things to do in Buenos Aires and where you want to go, because the longer you stay, the more free time you have to do things. Buenos Aires is a city full of museums and art, and it's an absolute joy to explore. Figure out what you want to do beforehand so that you can do it quickly and easily when you're there.
A lot of stores seem to be closed on Sundays and many museums are closed on Mondays, sometimes Tuesdays.
I think that the program really helped me to gain confidence in my Spanish-speaking skills and it helped me to get better at speaking and listening. I loved the museums and general culture of Buenos Aires. I definitely recommend this program to anyone looking to gain a once-in-a-lifetime experience and increase their comfort with and knowledge of Spanish. I loved the activities with the program and the flexibility and genuine friendliness of the directors and host parents. I also really enjoyed how we were given time to explore the city on our own, to eat out in restaurants, and to chat with our host parents. ¡Muchas gracias SolAbroad!
