I had to do an unexpected trip to Buenos Aires, and didn't have time to properly organize it. I opened the Airbnb app and looked for an apartment in Palermo, for one person. I scheduled for this, and hoped to be lucky... and I was more than lucky!
The apartment is just perfect for these cases. It is small, but 100% functional, with everything working just as it should.
The apartment is carefully equipped, with a good internet connection, a brand new air conditioner (really efficient and silent, it was a blessing in those hot, humid nights), a perfect bathroom, and a nice kitchenette with all you may need and more.
The building is great, with security 24 hours (very professional and friendly guys, too).
You have several amenities (such as solarium and a pool) although I only used the gym (which was pretty good too).
The location is excellent, very easy access and quiet at the same time. It is really a fantastic spot in the heart of Buenos Aires.
And the special highlight goes to the attention provided by Uriel and Angel: just *fantastic*. They were incredible attentive and helpful, truly amongst the best hosts I had interacted with. Legendary service.
So, to make this short: I don't think there is a better apartment in Palermo for one or maybe two persons. Top notch!
