We had the pleasure of having Alex (Alejandro Creus) as our guide in March 2012. Alex showed us around the city and was both professional and curtious. Upon meeting Alex he gave us many options to chose from during the eight hours we were going to spend together. We toured Buenos Aires, went for a lovely lunch did more touring and then called it a day.
If anyone is in the market for a wonderful tour guide while in Buenos Aires then look no further then Alex at Altournatives Travel and Adventure.
