This is one of the top best Airbnb's I've ever stayed in. The place is a relaxing oasis of an apartment that has been well thought out. The little plants inside and the greenery outside the window add to the calm.
The place is also very well located, close to everything in Palermo without being in a busy area.
And Natalia was amazingly helpful throughout my stay, answering my various questions before and during my stay, even helping me search for a long term apartment.
I would stay in his Airbnb anytime I'm in Buenos Aires :)
