We had a wonderful time. I think we were the only non-locals in the class, which was primarily young people (we are in the old fart category). The instructors taught in English and Spanish, but after a while I seemed to understand what the Spanish-speaking instructor was saying, as his demonstrations of technique were very good, and he used the same terms repeatedly. We enjoyed it so much that we are looking for Tango lessons here at home. The only negative was the facility. Old building (as is much of BA), second floor, no air conditioning, very crowded room. However, opening the windows at each end of the room helped a lot. Finding the dance studio was a little sketchy, as it is in a residential area and labeled only with a street address number. It shares space with a bar/restaurant that is downstairs.
