The place was almost perfect. The host (Nicolas) was pleasant, responsive, and professional. The place itself is modern and was "somewhat" updated. The apartment was not super new but more up-to-date than most AirBNB places in Buenos Aires. The biggest plus for me was how spacious it was. I have had some big disappointments on my first visits to Buenos Aires; very large prices for very small places but this one was refreshing. I felt I got exactly what I paid for and then some. Would definitely return.
I said it was "almost" perfect because the bedroom window is situated on the side of a busy street. It wasn't' too bad but I had to go to bed much later than usual and wait until the busy street was less noisy. Laundry facility (in the building or in the apartment) and a decent gym nearby was the deal maker for me.
I definitely would return and recommend.
