Natali was a wonderful host and very helpful throughout, including making arrangements (through her brother) for the ride to the airport while departing.
The listing was very accurate - the studio apartment is exactly as it looks in the pics. The place was cosy...a ceiling fan could have helped cut down the AC usage though.
The best thing about the apartment is the location - its only a 2 minute walk to metro stations as well as the Obelisk and has various shops/supermarkets/restaurants nearby. San Telmo/Florida/Puerto Madero etc are long walks away if you are so inclined. The area is well-policed and very safe. I would look forward to spending more time in Buenos Aires in the future and this is a good central place to explore the city.
