I wanted to find a good and convinient place to stay and work remotely and I found it.
The internet was super fast. It's 350-400 mbit/s. The apartment was bright with a pool and a patio on the top floor. I spent incredible evenings there.
Kitchen had everything you need. I cooked at home without any problem. You can prepare everything from pasta to grilled chicken there. If you don't want to cook there are a lot of really good restaraunts nearby. If you need anything, Cris responds in less than hour and very helpful and polite.
Here are restaraunts I recommend:
Urbano Cocina Americana - good ribs and salads (Montañeses 2298), 10-15 minutes walking
Fujisan - delicious sushi (Av. Mendoza 1650), 10-15 minutes walking
La Farola de Nuñez - average food, but perfect empanadas and superb waitress (Av. Cabildo 2899), 1 minute walking.
Plus there are a lot of places for shopping on Av. Cabildo. I enjoyed walks every evening. Unbelivable experience of staying in beautiful Buenos Aires.
