Carla's apartment looks exactly like the pictures. It is luminous and spacious. The location is great, close to the subway and close to restaurants and coffee shops in a great part of the city.
Carla replied promptly to all my questions, and she and Mary were available during my stay for any needs. My flight was delayed coming in and they waited for me to give me the keys. I had some issues with the kitchen and with lack of sheets and they took care of everything very promptly.
It is important to know this is a basic department, it has what you need but don't expect a high-end Airbnb.
All in all my stay was lovely and I would not hesitate to return to this apartment next time I'm in Buenos Aires.
