Oliver's apartment is just what we needed. It was well located and very comfortable. He was incredibly communicative and very patient with my flight delays. The apartment is right in the heart of Palermo Soho. This means you are just steps from endless options for eating, drinking and shopping.
A note about noise: This neighborhood becomes a hub for nightlife on Friday and Saturday nights. We had no problems with noise from the street. The bedrooms are in the back of the apartment and isolated from any street noise. However, both Friday and Saturday night someone in the building had a party and they shared a window with the same atrium as us and it was very loud. This is absolutely not a problem if you plan on going out and enjoying Buenos Aires at night. It's just something to keep in mind.
