“Mariel was recommended to us (three Canadians sharing an apartment) by the rental property manager in Buenos Aires. It was fortunate for us! Our abilities ranged from “beginning beginner” to intermediate. Mariel was able to tailor our two hour lessons to our different needs. She also modified her approach based on our daily experiences. She used a variety of techniques to introduce and reinforce. We were never embarrassed but were definitely called on to respond. She also left resources for us to use between classes and introduced on-line resources as well. Her fee was reasonable and her schedule flexible when needed. We would definitely work with her again.”Ken Haycock
“Mariel is not only an extraordinary person, but she is also an excellent professional. I hired her as an English teacher and I have always felt comfortable with her. She cares a lot about her material and about her planning. She is really patient and it is easy to follow her when she explains a new topic.”Jorge Luis Mendoza Bouroncle
“Mariel is a wonderful language instructor. She opened my mind and awareness to romance language through her Spanish teaching. After only 3 months my listening, reading and writing abilities surpassed what I thought I was capable of in such a short time. Her attention to detail, especially pronunciation, made all the difference in my understanding of the Spanish language. I specifically hired her to learn Castellano and she exceeded my expectations in all areas including cultural background of Latin American countries, common sayings in Argentina, and also unique deliverance of my weekly lessons. Mariel quickly discovered my personal learning style and adapted to my needs to ensure my success. I will continue to work with Mariel until I am speaking fluent Castellano and would love to hire her to learn other languages as well.”Sam Bonanno
“I went to Buenos Aires for a three days conference, but I stayed there a couple of weeks. Prior to my trip I searched for tour guide and I found Mariel on the net introducing herself as a tour guide. I hired her, and she took me to many places from the city of Buenos Aires. Mariel has been very professional the whole time. I met her every morning in my hotel and she showed me the city. She also helped me as an interpreter to communicate with locals whenever I had to do some shopping. I wanted to know some regional places and she managed to take me on a tour to San Antonio de Areco. She has been with me translating the local tour guides and helped me to communicate with other local people. I highly recommend her as a tour guide and interpreter.”Fahad Alhomoudi
“I was initially impressed with Mariel Olivera’s enthusiasm, communication skills and professional demeanor when I requested her interpreting services four years ago to guide my wife and me through Buenos Aires. During my visit I was able to become acquainted with this city in a way I never would have without her help. She proved to be friendly, knowledgeable and adventurous.
Mariel is reliable, dedicated and eternally upbeat. Despite being an hour late for our meeting, Mariel still waited until we arrived. She loves servicing the needs of the linguistically challenged, her English is excellent, and she is very good at what she does. I was also especially pleased with her surprise inside connection to the backstage of a tango show.
Of particular value to me was Mariel’s flexibility. Although she came prepared with a list of popular sights, we requested particular out-of-the-way places and experiences she had not planned for. Her ability to improvise allowed us a unique tailored encounter with the city. It is this kind of exceptional personal care that sets Mariel apart from the rest.
Organized and diligent, Mariel’s street smarts made us feel very safe, especially on the “Subte” and it is because of her excellence in this area that I was able to trust her to help us change money at a local banking establishment with a very competitive rate.
Mariel is a hardworking, top-performing service professional with a terrific personality. She has my highest recommendation, and I am happy to furnish more details if you would like additional information.”David Doering
“Mariel is fantastic as a professional and as a person. She is very polite and caring with her students, and responsible with her planning. Her English lessons have been very useful.”Pedro Arluna
Mariel was my tour guide when I visited Buenos Aires last year. Mariel was very knowledgeable about the city; from the architecture, historical landmarks, and cultural hotspots to various hidden gem restaurants and off the beaten path activities. She was personable and also professional. We visited museums, operas, monuments, as well as little shops, street fairs, and art galleries. Mariel provided interesting commentary and insight as my tour guide and helped make my trip a truly memorable experience.”Eric Lin
“Mariel is extremely personable and has a wealth of knowledge about her home town. She couldn’t have been more helpful in sharing the history of the city and and the providing some wonderful insights. She always provided great activities and I’d happily recommend her to travellers looking for to explore the city.”Dekan Apajee
