If I want to summaries my experience in this apartment and its hosts, Gaston and Barbara, I have to say I give them 6 stars out of five!
Both the apartment and the hosts were excellent and here is why:

— Apartment: The apartment is a very clean, modern apartment, with new everything (fridge, oven, bathroom and shower). The bed is a really comfortable king-size bed with an excellent mattress. We were there in winter so we could not use the pool but I assume you can use that in other seasons.

- Locations: The apartment building is located in a safe neighborhood (Palermo Soho) and it has a guard at the front door. It is in walking distance from some of the best restaurants in the city, many of them mentioned in the guidebooks as best places to eat in Buenos Aires.
The building is located between Italia Plaza and Cortazar Plaza. You have access to the metro and many bus lines to go anywhere important in the city. There are many shops and markets around the apartment. You can buy anything you need very easily. Location-Wise for a tourist this is the best place one can find in Buenos Aires.

- Hosts: Gastón and Barbara were THE BEST hosts you could find on Airbnb. They are really friendly, very helpful, and always accessible (they live nearby). They helped us with money exchange, gave us advice on places to visit and food to experience.
They have prepared a booklet for you with maps and everything to explore the city, and if you have questions you should not have any problem because Gastón and Barbara speak Portuguese, English, and of course Spanish.
In addition to everything I mentioned I had one more bonus: Gastón is a professor of history, and for a history buff like me that was a good opportunity to ask questions about the history of Buenos Aires and Argentina. We really enjoyed our conversations with Gastón and even had a chance to have lunch with him before we leave! If I go back to Buenos Aires in the future this is the place I go back to.
