I had a fantastic monthlong stay at Santiago's Airbnb and only wish that I could have stayed for longer. The apartment is a recently renovated and tastefully decorated unit within an elegant older building in a lovely neighborhood of Buenos Aires - some of the city's most beautiful parks are within eyesight as soon as you walk out the front door and turn to your right. The immediate neighborhood is relatively quiet but has a sprinkling of cafés, fruiterias, and restaurants that make it fun. The heart of Palermo Soho is 15-minute walk away so I found the location to strike a great balance of tranquility and proximity.
I really can't say enough about the interior of the apartment - it's beautiful. The pictures on Airbnb do a good job of conveying the feeling of staying there, in my opinion.
Santiago was consistently responsive and accommodating, checking in at intervals but mostly providing the space to get out and enjoy Buenos Aires. Couldn't recommend staying here more highly.
