This was an amazing stay in Buenos Aires! It was a 20 minute walk from the parks, about 50 minutes from the river. There is a supermarket right next to you, so it's easy to grab what you want and get back to the apartment in <5 minutes.
Wifi was fast (50mbps down, 30 or 40mbps up) and consistent. It was perfect to do video calls for my work. Apartment was well-equipped and Claudia is great.
