This apartment is located on the border of Puerto Madero, with all its fine dining, and San Telmo, with its bohemian flavor and street market on Sundays. It has a great view and is in a secure area as there is a federal police station one or two blocks away. The building itself has guards and is also secure with video cameras in the hallways.
Further north on Azopardo, is a place that makes great empanadas in the Tucuman style that I recommend.
Two blocks away is Paseo Colon, which has buses that go all over the city.
A bit further north is the Casa Rosada.
One thing to be aware of, it is loud in this part of the city. Every night there are loud horns from large ships. You can hear the street traffic. Bring earplugs!
