Patricia Kanelson and Sebastian von der Becke did a superb job of showing us Buenos Aires. They were on time and well organized. They informed us prior to our visit of the schedule and best way to spend our day. We felt we received a tour tailored to our interests and Sebastian even went the extra mile to spend additional time with us in the late afternoon so that we saw additional sights. We highly recommend them to help you with your time in B.A.
