This is my second trip to Buenos Aires and this tour has been by far the most memorable, worthwhile activity I've done. I can't speak highly enough of Elisa. Many people here won't, or can't, talk about the dictatorship, but Elisa told me incredible and harrowing stories about her own life, family and friends as well as explaining the backdrop of Buenos Aires in the late seventies/early eighties. Elisa brought photos, documents, audio testimonies, explained the murals on Olimpo and answered any question I had. For anyone who is interested in history, politics, culture, or or for those who want to learn about the darker, hidden side of Buenos Aires, or for an 'off the beaten track' activity, this tour is unmissable, and is a lot more personal and informative than a visit to the ex-ESMA. 10/10 - Brilliant.
