Hello! I have lived in Olivos all my life (I am 43). My seggestion is: find an apartment which is not located on Av. Maipu or Libertador (too noisy, too many strangers to the neighbourhood around), located between Av. Maipu and Libertador, and between , Corrientes and Moreno street. Please avoid Paraná street. (I live on Paraná). Since the tunnel under the railroad was built, we are in hell!). Paraná is the only street in the neighbourhood which unites Libertador and Panamericana without having to cross the railways. It used to be a perfectly quiet street, now there's cars and noise everywhere.
