Carlos was a wonderful host! He let us into the place early and responded to every email within hours if not minutes. He called a taxi service for us to schedule a time to head to the airport - which was extremely helpful since many of our cab drivers had a hard time communicating with us. I would absolutely recommend his place to anyone wanting to visit Buenos Aires. The location was close to the metro and a short walk to all the restaurants/bars/stores Palermo has to offer. In addition, the house was clean, large, and well kept. An absolute gem!!! :) (He even had an iron and a HAIR DRYER!!!)
