I had a truly wonderful tour of Buenos Aires with Katharina on August 18th, 2013. From start to finish, this tour was everything I had hoped it to be. Kat was warm, friendly, knowledgeable and provided us with great insight to all the sites on a well crafted itinerary that really hit all the highlights of BA in a comprehensive tour. The pacing was really wonderful as it allowed us to feel like we could leisurely linger at all the right places. I loved the lunch stop to sample the traditional street food. I was a bit concerned that the traffic and crumbling streets might create a hazard, but your the bike tour really made the most of the great bike lane infrastructure and quieter streets that I didn't even know existed. It certainly helped that we conducted our tour on a brilliant day in BA, but nonetheless, I would highly recommend this tour to my fellow travelers. Thanks.
