Rio&Learn is highly recommended by me! As a language teacher myself (I teach English here in Rio), I recognize the method of total immersion in the language and I find it extremely effective. Obviously it's tiring at first, but it's absolutely the best way to learn a language. During my private lessons, I have different teachers. I quite like this as every teacher has their own emphasis, specialty, and interests. All of the teachers are great teachers, though! They are all passionate about their language and culture, friendly, patient: everything a teacher needs to be. The school made me feel at home right away. Perhaps also good to mention: they helped me super quickly and effective with all of the paperwork needed from their side to obtain my student visa. Five stars, without a doubt 🌟🌟🌟🌟🌟

Had an incident with a holiday. I selected Monday and Wednesday for my classes, since I can’t attend classes on other days. Due to holiday one of the lessons was scheduled on Friday. I warned about this issue on Tuesday, 3 days before the lesson, but manager answered in a rude way that they can’t do anything and blamed me that this is my fault I didn’t warn earlier. Teacher is asking their students to give good grades to the course on a second lesson. This is not teachers fault. Probably managers ask her to do this. Maybe my grade will change. Only time will show. At the moment as is.

Estudar portugués online com a escola Río & learn é muito gratificante pra mim, pois as professoras são amorosas. As aulas são engraçadas, com muita prática falando português brasileiro. Também eu posso conhecer pessoas de outros países e outras culturas. Eu sinto que moro no Brasil quando eu estou em aula!!
Raccomando tantissimo! Ho fatto lezioni private e il mio portoghese migliora a vista d'occhio. Fluente in 4 mesi grazie a questa scuola <3

I took a one week in-person course and had an amazing experience. It was intensive and definitely highly recommended! I appreciate the great, caring and highly professional team : Diogo for your awesome and energetic lectures and dedication. The lessons outside the classroom were very engaging and a useful way to immerse into local life. Thanks Laise, Marta and Dayane for the great support and smooth coordination. I look forward to taking the online sessions next!

I joined the online classes 1 month ago and I am loving the experience. Shout-out to Professora's Dani & Nathalia,they're amazing! The classes are interesting,focused and the teachers are very patient. They also do extra online activities outside the class schedule to really boost your learning in a fun, engaging environment. My speaking proficiency is improving faster than ever before compared to other classes I tried with other schools. The staff are very organised, communicate well and I think the cost is excellant value for money. Vamos lá!

Followed one week of group classes in Rio de Janeiro, I had no prior experience with Portuguese. The classes were really good, fun even (we laughed a lot) and the material is very well chosen. The after activities (Rio Live) as well were so fun and the teachers (Diogo) always made you feel comfortable and had a lot of patience. We even went for lunch together to learn about this subject. I really loved this way of teaching. I feel like I have a good base of the language and I can understand so much more now.
I have taken online courses twice now with Rio & Learn. In both group and private lessons the instruction was excellent. Classes were well-planned and the instructors were responsive and engaging. If I ever have the chance I will definitely sign up for their in person classes.

Ich war vor 4 Jahren dort und habe dort die Basics in Portugiesisch gelernt. Sehr praxisnaher Unterricht mit vielen Aktivitäten und Spaß. Mir gefällt dieser spielerische Ansatz sehr und ich konnte einiges lernen. Absolute Empfehlung!

This is the best language school ever. I spent one month, started with no portguese whatsoever, and now I can hold basic conversations and understand most of what people are saying. My progress was pretty amazing thanks to all the teachers who are AMAZING. I can't stress enough how nice, helpful and fun they are. In addition to classes in the mornings, the school offers different kinds of activities every afternoon outside the school. It's great to practice portuguese outside and also discover some great places in Rio as well as many different kind of fun activities. I made great friends there and had so many good laughs. Often the teachers also take you out of the classroom for the entire class or half of it to make it more entertaining. I truly recommend this school that was way more than a school for me. Thanks to everyone there, especially Diogo, Lais and Guliana for everything.
