Spanish tutors in Mexico City bring advanced degrees in linguistics, philosophy, and Spanish literature, adapting teaching approaches in real-time during personalized sessions. The program operates from a boutique hotel in Polanco where adults who learn Spanish in Mexico receive two hours of morning instruction and two hours of afternoon sessions, alternating between private coaching and strategically selected small group workshops. This intensive approach—combined with pre-arrival Zoom sessions, Spanish-speaking lunches, and evening cultural programming—creates conditions participants describe as the most effective immersion available for serious adult learners.

Eric H. | New York City, NY

“As a high-intermediate Spanish speaker already going into this experience, I was curious about how much I would gain from the language instruction provided by Fluenz. First, I would highly recommend starting with a package of 5 or so online classes prior to the start of the immersion so that you can get a sense of their pedagogical approach. I felt like this super-charged my learning going into the week and helped me get to know the teaching staff a bit before I arrived. In fact, their approach involves precise coordination of the instructors and a hour-by-hour monitoring of the teaching plan, tailoring it to what each student was needing in order to optimize the time spent in classes. I never felt that a teacher didn’t know precisely where I was in my learning process. What’s more, there were many times in which they would remind me of a small detail from our conversations, from a subtle error that I made to a random detail of my life. It’s highly impressive that they offer this level of attention, and I think this is what makes this talented team so effective.”

Julia Vitullo-Martin | New York City, NY

“We were in great shape for the arduous, productive week to come–two hours of individual instruction in the morning, a 90-minute Spanish-speaking lunch in the garden, and two hours of group instruction in the afternoon. By the closing session–for which we all write & present an essay in Spanish–Jen & I had both made huge leaps forward.”

Julia describes this as her second Fluenz immersion in Mexico City, noting the intensive nature of the daily schedule combined with thoughtful cultural programming.

Lisa W | Chicago, IL

“In every outing, every one-on-one Spanish class and all of the group classes, as well– so much thought and care was put in by the Fluenz staff. Personalized touches were somehow at every turn, even as the staff juggled a roster of 22 students, its largest ever. Both of our experiences were spot-on, choreographed with care, intention and specificity for our differing levels.”

Lisa brought her husband who was a complete beginner while she possessed near-fluent abilities. The intensive personalized instruction accommodated both levels successfully.

“Classes were one on one and group. If I had to criticize one thing, it would be that there should have been a better balance of one on one instruction across the group. I was grouped every afternoon whereas others were not. I thought by the last day an effort should have been made to make sure I and the one other student who were grouped got one last one on one.”

Felicia’s feedback demonstrates the program’s commitment to one-on-one instruction, with her desire for even more individual sessions indicating the value participants place on personalized coaching.

Barbara H | Oaxaca, Mexico

“The teachers were all attentive to where I was with my language learning and adapted classes daily to my level. I really appreciated the fact that they worked with all of us students at each of our different levels. The teachers all knew HOW to teach, pushing me further, yet encouraging me along the way. For example, when my brain started to freeze up on day four, my teacher just switched to a Spanish conversation allowing me relax and then move forward with the lesson.”
