This apartment was great for stay in Buenos Aires! It was walking distance to a subway which got me just about everywhere and a short walk to a large strip of restaurants in Palermo. Carlos was a great host and very responsive to my questions. My only suggestion for future travelers is that this may not be a fit for you if you are a light sleeper. It is a city apartment in the second floor and the street sounds can be pretty loud at times.
If you can deal with some city noise this apartment is a great stay.
