Stayed for 3 weeks and they organized someone to clean the apartment and change bedsheets and towels once per week (3 times), free of charge, this has never happened before in an Airbnb. Absolutely outstanding.
Clean, great location, easy access, comfortable.
My only negative point is that if you are in Buenos Aires to enjoy the nightlife and intend to sleep past 0800am this may not be the place for you as the roof starts to crack A LOT once the temperature increases, it is a loft without a ceiling, which makes it very hard to sleep. But because I was there for work it did not affect me much except on weekends.
