I stayed in this flat for a couple of months in October/November 2015 while I was doing some courses and I couldn't be happier. The flat is perfect for one or two people and is fully equipped, very clean and modern; the pictures posted accurately reflect the place. It has a Jacuzzi on the rooftop and also a small gym in case you want to burn some of the amazing food you can find in Buenos Aires.
It's in a prime location in one of the best areas of Buenos Aires, everything I needed was right next to the flat, I didn't even have to leave the block ("cuadra" in Argentinian) - supermarkets, laundry, restaurants, bars, parks and gyms. I could call and get any type of food delivered from loads of different places all around the area - from "empanadas" to sushi. It's very well connected, next to loads of buses that take you all over town and a short walking distance to the tube; and next to the tube is one of the best malls in the city "Alto Palermo".
If you like walking (like me) you can get to the "Bosques de Palermo" really quickly and enjoy loads of museums that are close-by like the MALBA, or go to the japanese gardens, and if you feel like doing a long walk you can go through "Avenida del Libertador" straight into the city center.
I would definitely recommend the place and will stay again next chance I can come to this amazing city.
