I stayed at this Airbnb for a combined three weeks over the course of two separate stays.
This Airbnb was absolutely perfect for me. The apartment was clean and in a great location - it was very safe and close to countless restaurants. There are also many bus stops and grocery stories within a block or two. The WiFi was ultra fast (which was great for a couple of business meetings that I had)
Gaston was very friendly and helpful - he even let me check in early for both of my stays. I highly recommend this Airbnb and I hope I can stay there the next time that I am in Buenos Aires.
