I highly recommend Sebastian's place. Aside from offering an amazing AirBnb property, both Sebastian and Vari were incredibly hospitable and helpful. Sebastian's place was PERFECT! Located centrally in Palermo Hollywood, it is a hop, skip and jump away from all the best bars, restaurants and cafes! The apartment itself was AMAZING. Located in a newer, upscale complex which featured a rooftop pool overlooking Palermo Hollywood. Vari and Sebastian were incredibly helpful and flexible too, offering me wonderful recommendations and solutions to a few hiccups I encountered (not related to their unit) in Buenos Aires.
If I'm back in Buenos Aires, I will definitely check if this unit or any of Sebastian's units are available.
