Ralf and his team are excellent all around - he's a an airbnb "superhost" for a reason! I travel to Buenos Aires often for work, and I always stay with Ralf at Palermo Torre Uno. In addition to being a first-class host, the apartments that Ralf has feature amazing view of the city, and the location can't be beat. Palermo Soho is the best place to stay in Buenos Aires in my opinion - full of top restaurants, great cafes, and arguably the best parks in the city - the Botanical Garden and Japanese Garden - are very nearby. Also, the subway and bus lines that run through Plaza Italia, just two blocks from the apartments, provide easy access to all of Buenos Aires. Highly recommended!
