Carlos met us early in the morning (2:00 am) on the airport even that our flight was late. He was very enthusiastic to show us around and give us essential information.
Apartment is exactly as shown and described and served all our needs well (we are family of four, children 13 and 16).
Location is perfect, in Microcentro. We never felt unsafe. There is few minute walk to Florida street, shops, restaurants, Galeria Pacifico, theatres etc. You can easily walk to San Telmo, Recoleta, Puerto Madero. Best for tourists.
