Carina's place was by far one of my favorite apartments while traveling in South America. Most Airbnb apartments usually have the bare minimum suitable for living, causing the home to be lifeless and impersonal. This one felt alive, everything from the books to the artwork, even the coasters. I loved every aspect of this apartment. I would definitely recommend anyone traveling to Buenos Aires to stay at this apartment.
Although I didn't have a chance to meet Carina, her communication was superb. She would always promptly address any silly questions I had such as where the closest bank or supermarket was. Mini markets were abundant within a block or two radii. A larger supermarket was only a few more blocks away.
Most banks around that neighborhood did not support an international debit card. I was having trouble with the Banco (Red B sign in front of the bank) system. The Link system seems to work without any issues, so if you're having trouble with the ATM, go to "Banco de la Nación Argentina" or find a Link system. They are more in abundance near hotels and touristy areas.
As for the neighborhood, it's relatively quiet compared to the urban cities in the States side, but it felt safe enough to walk around at night. There were plenty of restaurant choices for lunch and dinner once you learned the neighborhood. I especially loved Bio, the organic vegan restaurant, directly across the street. The one thing that threw me off about Argentina on my first few days was that most restaurants open at noon and close shortly afterward and reopen at 8 PM. Foursquare became my go-to resource in seeing if stores were opened.
There's also an outlet mall a few blocks from the apartment, which was a pleasant surprise.
As for the apartment itself, the kitchen was well equipped with the essentials. All the pots, pans, silverware and dining ware were in excellent condition. There was a generous amount of toilet paper and paper towels for our one week stay, whereas most places would only supply a single roll.
We never ran into any issues with the WiFi; it was around the 20 - 30 MBit range. There wasn't any WiFi in the bedroom, but that wasn't too much of a problem.
Overall, if the apartment is available. Definitely reserve it; you won't regret it!
