On our first visit to BA in 2016 we took the full day tour (spread over two half days, perfect for us with the warm weather in February) with Jack. It provided us with a great orientation of the city and hit many of the highlights, including Recoleta Cemetery, Plaza de Mayo, la Boca, San Telmo, and many others. We mostly walked, but also rode the bus and subway, and took a taxi. At the end of the tour Jack helped us get a bus pass that we used for the rest of our stay. The tour was really informative and the pace comfortable. We also took the day trip to Colonia del Sacramento in Uruguay with Oliver, where we learned about mate and had a memorable lunch at a local restaurant.
When we returned to BA this March, we asked Buenostours what they could offer. They designed two tours ( with Richard and Don) for us that highlighted neighborhoods away from the more heavily visited areas. After having four great tours in a row, we did the Tango Tour with Liz, a great way to be introduced to BA after dark and to find milongas that would be difficult to find without local help; and we did the Asado Adventure with Frank, a great introduction to Palermo and the grilling culture of Argentina - plus a great meal!
Each tour provided what felt like an insiders view of the city, its neighborhoods, and history and culture. If we return again to BA, we will see what Buenostours can suggest.
