We had a wonderful stay at Ralf’s place in Buenos Aires. Both Marcelo and Ralf were very kind and hospitable, and the apartment was nice and comfortable. We felt right at home. The neighborhood is fantastic and the building itself is incredibly safe (gated, 24-hour security, etc.). I never felt unsafe in Buenos Aires, but Ralf’s place is a safe, quiet oasis in the middle of a bustling neighborhood. Highly recommended.
