Very cool refurbished loft. Two levels with a rooftop patio, tons of light, and open air. Extremely comfortable. Gema is a great host and was extremely flexible despite a delayed commute from the airport.
The area more of a business center but a couple blocks away is a shopping 'mile' (Florida Ave.), Plaza San Martin is just a couple blocks, Teatro Colon and Obelisk, and Casa Rosada are just down the street. There are plenty of places to eat both cafe's and more formal restaurants. Taxi ride to Palermo is ~US$7-8 and most else is closer.
