We had a very good tour with Ariel before our departure on a cruise. He was easy to communicate with and happy to customize our tour. He met us at our hotel with a driver which made walking around some of the major sites very easy. He knows about the history of the City and the present day living there. He was able to answer all our questions. He skipped some places we were not interested in visiting and dropped us off at the cruise terminal with our luggage. He is one of the best tour guides we have hired and I can recommend him to anyone visiting Buenos Aires.
